i'm having fierce trouble trying to obtain information as to the peaks/bonds in the IR spectra of the following; benzaldehyde, cinnamaldehyde, benzophenone, cyclohexanone and acetophenone.

i keep typing in plenty of the keywords in the various search engines but to no avail.

all i need is a rough guide as to which peaks belong to which bonds!

can anyone provide a decent link to help me out?
thanks

Try the sadtler database or the NIST, I think Merck and Aldrich has some good databases for these types of spectra. The thing is, they may have obtained the spectra in a different context, such as different solvents, for which there may be shifts in the wavelength peaks.

If this was for an experiment, you should have obtained each respective compound spectra independently.
 
IR spectra are usually observed with neat material if they are liquids or oils, which all of those are. You should certainly check to see that the specta are neat, however.

You should check out the SDBS, they have tons of IR and NMR spectra for common compounds.
