Spectroscopic Studies of Substituted Benzalanilines

Abstract

Ultraviolet and visible spectra are reported for 28 N-benzylidineanilines with their molar absorptivities given in absolute ethanol, and in isooctane when feasible. Infrared studies in the 2–15 micron region are reported for these compounds and also for three newly synthesized N-d-benzylidineamhnes. With the aid of these deuterated benzalanilines, infrared assignments are given for the frequencies characteristic of the center —CH=N-azomethine group. The ultraviolet and infrared spectra are compared in relation to the reported basicity of their azomethine groups.
