摘要
Remarkable changes in the (N)CH3 stretching wavenumbers have been observed for amines on protonation. These C-H stretching wavenumbers are related linearly to the corresponding C-H bond lengths calculated by the ab initio method. The (N)CH3 stretching bands are useful for distinguishing between free and protonated amines.
