Help interpreting IR spectrometer graph
« on: September 27, 2016, 01:13:40 PM »
Hi everyone, and sorry in advance if this is not the correct forum or if my question is too basic, it' been years since I took a chemistry class and my knowledge is too rusty.
I'm trying to interpret this graph http://i.imgur.com/bbxr1VX.jpg (spectra of docosane). From what I gather, the peaks indicate I have aromatic bending C-H, aromatic bending C=C, and alkyl C-H stretch as functional groups, and my graph is congruent with the IR spectra of docosane I found online.
My question is, how do I factor in the kubelka-munk scale? If I'm correct, it's similar to absorbance but I couldn't find clear information online. Also, do the functional groups I mentioned make sense? I believe the functional group of docosane is methyl.

Maybe I'm wrong, but docosane has no aromatic groups, its just a straight chain hydrocarbon.
When in doubt, avoid the Stille coupling.
