I am taking a course in structural determination of organic compounds. Right now, we are giving the IR spectra.
I am looking for a table, as detailed as possible, of the absorptions. I hope you can help me.

A very nice comprehensive set of IR absorption group frequencies were compiled seventy decades ago in the Journal of Optical Society of America by Colthup, 1950, 40, 397-400.
It is freely available if you search "Spectra-structure correlations in the infra-red region" by Colthup in Google Scholar.
You should memorize some standard frequencies of very common functional groups.
