WebApr 1, 2002 · A signal is only observed in the IR spectrum, if the dipole momentum of the molecule changes during the interaction with the electromagnetic radiation. This is very likely for groups which already possess a significant dipole momentum to start with e.g. C-O, C-Cl, O-H, etc. (strong peaks). http://www.chem.ucla.edu/~bacher/spectrocopy/IR1.html
