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.

  • $\begingroup$ I recommend you stick to the table your prof gave you, because that is the one that will have to do when you have your exam. Otherwise Hesse, Meier, Zeeh surely has an English edition nowadays. $\endgroup$ – Karl Nov 11 '20 at 19:58
  • $\begingroup$ Thanks @Karl for bringing this book into my attention. It is highly rated on Amazon. Will try to buy it one day. $\endgroup$ – M. Farooq Nov 12 '20 at 1:59
  • $\begingroup$ @Karl Of course there is (some of the entries here). I like to complement HMZ with Ernö Pretzsch's compilations from the other school in Zurich, too (Springer) and still have an edition with the CD. $\endgroup$ – Buttonwood Nov 12 '20 at 11:06

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.
