IR Spectroscopy

I am not studying for the MCATs, but I am taking organic chemistry right now. We learned infrared spectroscopy last lecture, but I got lost pretty quickly.

Is there a video out there that can teach me the basics? I can't seem to find some. I looked around Khan's Academy as well as reputable users on YouTube.

Hmm, I don't know of any videos but do you have a question?

Don't worry, I felt the exact same way after learning it in Org2. The only thing you can do is practice practice practice for spectroscopy. It's kind of like learning a new language.
IR on the MCAT is a lot simpler though so don't get too worried if you see some complicated stuff in your class.

Yeah this just takes a lot of practice. Get to know major groups when you see them (especially carbonyls.. I've never had to differentiate carbonyls from one another on any sort of MCAT practice afaik, even though my professor insisted we knew the finer points of where different carbonyls would land in comparison to others ~1750), and just think of them as a logic puzzle. I was freaked out with them originally, so I did some examples and found they were right up my alley. I enjoy puzzle questions.

+1 for freelanceteach. This guy is amazing xD. His videos helped me so much for the MCAT.

Freelance teacher is pretty good. Also look up spectroscopy questions online. It'll make NMR, IR, UV-Vis, and mass spect really easy if you practice a few problems. Hell it becomes fun after a while.

The main things I would suggest for you to remember is the wavenumber for some special functional groups.

So remember carbonyl occurs around 1700 cm^-1 and alcohol around 3200-3600 cm ^-1! These are very very important. Most all of the Orgo questions I have encountered are about these two groups.

Other than that, remember C=C, C=N, C - C triple bonds, C - N triple bonds.But even these, I have rarely seen. In most tests, I have seen mainly carbonyl and alcohol Qs.

Obviously, though you definitely should study it in a bit more detail if you get the chance.

I need to know the basics. I get that a higher wavelength is needed to stretch/bend a molecule if the molecule has double or triple bonds. Well, that's about it...LOL

All the examples and explanations I have found go straight into analyzing graphs, but I need to know what I'm supposed to be looking for first....

Anyways, I'm just going to go read my textbook and get more confused..LOL
