INTERPRETATION OF INFRARED SPECTRA, A PRACTICAL …
www3.uma.ptThe fundamental requirement for infrared activity, lead-ing to absorption of infrared radiation, is that there must be a net change in dipole moment during the vibration for the molecule or the functional group under study. Another important form of vibrational spectroscopy is Raman spectroscopy, which is complementary to infrared

www.cpp.edubands may confuse the interpretation. In very symmetrical compounds there may be fewer than the expected number of absorption bands (it is even possible that all bands of a functional group may disappear, i.e. a symmetrically substituted alkyne!). Infrared spectra are generally informative about what functional groups are present, but not always.
