Abstract
Calculation of the IR absorption bands intensities has been carried ou t by benzylideneaniline and its five fluoroderivatives. It has been sh own that the strength and polarity of the C=N bond hardly depend on el ectron effects of the substituents. The change of nu(C=N) intensities in the compounds investigated are mainly due to the variation of vibra tional forms upon substitution.
