Ok, watching this again I see that I was too excited to talk about my own experiences with spectroscopy, and that this will probably answer all the questions I had. Honestly though, a suggested text on this subject would be super cool, if you haven't already posted it 😅 proven that i'm terrible at noticing some details or intentionally overlooking them

Comment drleted because i didn't understand that this is wildly diffeent than diffraction and fluorescence. I think I understand my misconception on a physics level, just assuming that all radiation is the same which was obviously the first stumbling block... Would love to hear where else I failed! And please be mean 😂 that's how i remember

You're right that all electromagnetic radiation is the same, just different energies, wavelengths, frequencies, etc. This video is more about the mathematical description of molecules that allow us to predict whether they will be IR and Raman active. It turns out that mathematicians studying linear algebra helped chemists out in this regard through what's called "Group Theory." This is basically the pinnacle of chemistry knowledge though and only something someone studying Inorganic or Physical chemistry would need to know about.

@@rojaslab hoo boy feel like I'm stumbling into graduate material here and I love it. My fave math instructor, took diffeq and linear algebra among several of the other precursors with him, was a huge fan of group theory and loved working it into the material as much as he could. I was not expecting that to be mentioned heh 😅 I wish to good lerd that I was in ochem2 this semester like I was supposed to be! I've seen Brandon's lecture slides and he has them going from a profile to predicting structure on the first day, and vice versa. I don't know if that's standard, but my experience from the dry end of things says you need at least a fast Fourier transform to get an idea of where the signals are coming from. I obviously need to do a lot of reading because Brandon doesn't post his lectures and there's no text assigned for the course. If you could recommend a resource to nail down what I'm missing with these seemingly simpler profiles (easy enough to eyeball for an exam 🤔 seems strange but apparently how it works on wetside) that would be amazing!
