An Infrared Study of the C=N Stretching Frequency in N-Benzylideneaniline Derivatives

Abstract

A series of 131 N-benzylideneaniline derivatives was prepared, and their infrared spectra were measured in the same conditions. Statistical tests showed that differences of substitution in benzene ring of benzylidene group affected acceptably on the region of C=N stretching absorption peak, but those in benzene ring of aniline group had smaller effect on it.
