Sample IR Spectra: By looking at IR spectra that contain known functional groups and comparing and contrasting them with other IR spectra, one can develop the skills required to be able to "interpret" an "unknown" IR spectra. such sites. Knowledge is an endless reservoir so whenever you think you know everything about a particular thing then you need to think again. 23 ( t, 1H), 10.
