Having taught spectroscopy for several years, I find that students commonly have a hard time prioritizing IR bands in their spectra interpretation.  After several false starts and long years of procrastination, here’s a pictorial guide that I hope would be clear, accurate, and helpful for learning to interpret IR spectra.  If you wish to use this for print, the PDF version would give better resolution and can be found here.

In Portuguese, translated by Vitor Ribeiro.

In German, translated by Robert Herzog.

In Spanish, translated by Henry Hughes (UNGS Argentina)

Can you “speak chemistry” in a language other than English? Let me know if you can (and want to) help translate this image.
