ir spectrum


12/10/16 As I’m trying to post something everyday here’s a glance at what my first day in labs consisted of. Left: my friend found mysterious crystals forming in her glassware after she completed a reaction so she ran an IR to see if it was anything interesting. Right: my (already) messy lab book where I wrote down the names of all the surfactants I’ll be studying for the next few months.

Let’s talk about being organized and how to create an efficient system for your chemistry notes!

I will be the first one to admit that I’m not always organized or put together. Though in retrospect, I should’ve been because it saves you 87684 hours when you sit down to study for an exam. On that note, let’s get started!

Binder/Folder/Notebook Organization

  • Color code the subjects to match folders and notebooks. What I mean by this is to have a purple folder to match your purple notebook for chemistry. This system really helped me organize my subjects by color and quickly access them when I have to do homework or look over notes. (On top of that I like to use the same color when writing in my planner for due dates!)
  • Divide your binder into sections. Try to be mindful of over using colors on this part. It can start to get messy if you use the color system for your subjects and then another color system within that subject. Let me give you an example for chemistry:
    • General Notes - this includes basic stuff like vocabulary and theories. 
    • Nomenclature - keep it simple and just continuously update it. 
    • Reactions - put headers on the paper with what category these reactions fall into (Synthesis, Carboxylic reactions, Amine reactions, etc.)
    • Instruments - this relates more to an analytical chemistry class or an organic class, but don’t forget to include some pretty illustrations and sample spectrums. 
    • Handouts - organize them by chapter and put answer keys behind each one if given.
    • Quizzes/Tests
  • Create a binder cover. These are fun to make because you can either draw it or print out an already made cover. I usually find a pretty font and colorful background.
  • Buy a separate binder to store old notes. So this is good for people like me that hoard their notes… and only use notebooks during the semester. When I finish a semester I usually have assigned binders to store my notes. For example, I have a 3-inch binder for ONLY general chemistry notes/tests/handouts. Then I have a binder for ONLY organic chemistry notes/tests/handouts. This system has made it extremely easy to store my notes under my bed and then pull them out when I tutor students!

Chemistry Note Organization
(This can easily work for any other subject, but I’m going to stick to only chemistry-related for this post!)

  • Embrace the color system. Like I said before, don’t try to overdo it but adding colors in chemistry notes make it easier to follow. My prime example for this is organic chemistry:
    • Write non-carbon atoms in blue, purple, or green. Maybe do halogens as blue, oxygen/sulfur as purple and nitrogen as green. Do whatever works for you!
    • In a different color pen (black if you write in pencil), write the solvents used to perform the reaction. I don’t know how many times I forgot to look out for solvents because I read right over them…
    • In arrow-pushing mechanisms, I really liked to draw the arrows in red. This allows you to see how the reaction scheme works and what atoms get eliminated, substituted, or added.
    • Label compounds/ions if they’re either an electrophile or nucleophile. Another thing I commonly read over because it blended in too well with my notes. The first-semester organic chemistry class is really heavy on knowing these terms and being able to identify them. 
  • Highlight key terms. Pretty obvious but I know some people who have notes that are nothing but in pencil. I honestly don’t know how they can read their notes and study them…
  • Date and put headers. Another pretty obvious thing but sometimes it’s hard to keep track of what you need to focus on for a test. I usually go off dates and start with the first lecture after a test!
  • Get creative and draw illustrations. It spices up the notes and sometimes it’s better to study with a picture. This works well with theories like the Bohr model! Maybe even draw your own little IR spectrums or NMR peaks. I did that when reading my secondary organic chemistry book. Oh, and why not put some color in those illustrations as well, haha.
  • Annotate equations by circling variables you don’t know. I’m currently doing this for my analytical notes and it makes understanding the equations so much better! I can go back and see why or what a certain variable is being used.
  • Use margins to annotate. When going back at study notes, it can get crammed if you annotate them all over the pages. So try to create a column only for these side notes.

These are all the things I can think of when it comes to organization. If you have anything else to add, please feel free! Hope you enjoy. :-)

When Jemma got the news, she knew exactly where she needed to tell Fitz her little secret. What better place to tell Fitz about the next chapter of their lives than the place where it- where they- truly began.

Jemma wasn’t even sure the exact condition of the S.H.I.E.L.D. Academy of Science and Technology in light of the events of the past several years. But, after a few phone calls, and not to mention her pull as a very prominent past-student, Jemma was given permission to bring Fitz to the Academy in the late dusk of a cool August evening. The halls were deserted, with not a single student or professor in sight, but everything seemed to be exactly as Jemma remembered it.

As she led Fitz down the quiet Academy hallway, she could tell that even though he was blindfolded to keep their destination a secret, he knew exactly where they were. As soon as they had entered the Academy, Fitz’s grip on her hand had tightened, his fingers wrapping more securely around her own and the cool metal of his wedding band pressing into her palm. Even without seeing it in front of him, the building was so familiar to the both of them that he knew exactly where he was based on smell and sound alone.

Ace, Aro, and Poly Soulmate AUs

(I see them occasionally, but come on. Everyone could use some more.)

((This masterpost was used as inspiration/reference.))

  • Asexual folks who take comfort in their countdown/first words/last words/whatever marker you prefer, because it means they have a soulmate out there.
  • Aromantic folks with bare arms and proud.
  • Polyamorous folks with two or three or more markers
  • Platonic and QP soulmate tattoos that are visibly different from romantic soulmate tattoos–white ink, or written in what looks like Sharpies, or on the opposite arm or on the palm of their hand
  • Demisexual/demiromantic countdowns that hit zero not when they first meet their soulmate, but when they fall in love.
  • If tattoos are animals or symbols or tell a story, then poly sleeves to tell a much bigger story
  • Gray-ace/gray-aro marks that fade, or change, or might be a birthmark actually, if you squint
  • Demi countdowns that count up and stop when they fall in love
  • Someone who has two countdowns, perfectly in sync, meeting two people, each with a perfectly synced countdown next to one that already reads zero
  • Aros having a spade tattoo
  • In a world where you only see color once you’ve met your soulmate: some people are born seeing color; some never see color and don’t really care; some never see color but are born seeing in the UV or IR spectrums; some people see a little bit wider spectrum, or a little more vividly, with each soulmate they meet

Hello Studyblr Community,

Just wanted to send out a little note - a friendly reminder - that if you have any troubles in a chemistry course or chemistry related topic feel free to send me a message. While my studyblr is here for personal motivation to finish up my undergrad, it’s also here as a resource for anyone who struggles or needs some simple help in chemistry. So far I have taken both general chemistries which cover topics ranging from unit conversions, titrations, ideal gas laws, molecular geometry, and intermolecular forces, *The list continues and I have multiple study/cheat sheets for many of these topics since my lecture was student-based teaching. Also, I have completed the first semester of organic chemistry that includes resonance structures, chirality, nomenclature, SN1/2 and E1/2 reactions, and alcohol synthesis. Right now I am enrolled in the second semester of organic chemistry (currently making a solid B in case you wanted to know how reliable I am with my knowledge) and have covered ether synthesis, aromatic nucleophilic/electrophilic substitution, activation/deactivation on the aromatic ring, amine synthesis, aldehyde/keytone synthesis, carboxylic synthesis. Next semester I will begin advance organic structure studies that include UV spectrum, proton and carbon 13 NMR, mass spectrum, and IR spectrum. Though I am already confident with handling those instruments and can help anyone who needs an understanding of how to label peaks or knowing what an unknown compound contains. On top of that, I will be taking analytical chemistry next semester as well. 

Of course, the list continues because I will always try my best to answer any chemistry related questions that my followers have. (Google does wonders for me and I have a good way of finding amazing study guides) So please don’t be shy when asking questions or correcting me when I’m wrong. I don’t have my degree yet in chemistry so I’m not always correct! :) Love you guys and keep up the good work. [Link to my ask box]

*It would be awesome if everyone could spread this little note so I can help anyone out who needs it. I hate to see students struggle in chemistry when I am currently on my way to becoming a teacher.  

excuse the potato quality… but i’m thinking of calling this toluene, but i wanted some opinions first :). fractional distillation lab, unknown mixture of 2 liquids. first fraction DEFINITELY ethanol. this one boiled off at 104 degrees celsius, so i was thinking propanol at first but this is definitely not an ir spec for propanol lol. i don’t think we did a wonderful job with the last fraction, i think we boiled too quickly, but that’s okay per my instructor, as long as we know what we should do in the future to make the experiment more successful.


Why Hubble will never see the first stars

“And so while Hubble may never see the first stars, it’s brought us closer than we’ve ever been before. When the next generation of space telescope comes online, it’s a certainty that we’ll see farther back that humanity ever has in the Universe’s history of forming stars. And if we get lucky, we might make it all the way back to the very first ones.”

The Hubble Space Telescope is an amazing piece of equipment, and has seen more distant stars and galaxies than any telescope before or since. Earlier this year, it broke its own cosmic distance record by discovering a galaxy at a redshift of 11, back when the Universe was just 400 million years old. Yet the first stars should go back even farther, and Hubble will never see them. Thanks to a combination of the fact that the Universe is not yet ionized and therefore transparent to light, and also that Hubble can only peer a little bit into the near-IR part of the spectrum, stars/galaxies at redshifts of 20, 30 or even 50 will never be seen by a Hubble-like telescope. But James Webb has a chance, and even if it fails, it will surely get us closer to the “first stars” than Hubble ever has.

It’s an amazing time to be alive, and if you weren’t yet excited about the 2018 launch of JWST, it’s time to get your motor running!

“A seat with a view.”

Hello there! My name is Connor, and I’m from Toronto. Most of my work is in full spectrum light, but lately I’ve been trying to hone my infrared skills, as seen above. I use a Nikon D5000 converted to full spectrum (IR-Visible-UV) and a D7000. I’m still very much an amateur, and only do photography in my spare time as a hobby.
