Accurately and Quickly Interpreting NMR/IR Spectra

[biochem850]

In examining the IR spectrum, I noted that there were peaks for CH2-x where x is bromine, methylene (2 peaks) and a peak corresponding to a methyl group; I concluded that I've synthesized n-bromobutane. Is the method I used to interpret my spectra sound? *CDCl3 was the IR solvent

In addition, in looking at the HNMR spectra, I concluded that the protons shown in the NMR spectra corresponded to the groups determined in the IR spectra. My only concern is that the approximate ppm(s) seem to be shifted yet I know that this may not necessarily mean that my interpretation is wrong. Can someone confirm that my logic is sound and supported?

I've attached the NMR and the IR. http://i42.photobucket.com/albums/e309/Alex_Jsoh/IRSpectrum-page-001_zps084bb818.jpg

Thanks!

What is n-bromobutane?

 

[biochem850]

I'm sorry, 1-bromobutane (or n-butyl bromide).

Is the rightmost small peak CDCL3? Maybe you should set it to 0?
If so then it works well with the 1-bromobutane.

Can't really see your IR spectrum very clearly, but it does look similar to the reference IR spectrum for 1-bromobutane.

Yeah, someone else did the IR/NMR for me.

The smallest peak is CDCl3 and it seems that setting it to 0 is prudent.

I did some thorough review of NMR/IR and I'm pretty confident now!

Thanks guys!
