✦ Synopsis

A zero-order normal coordinate analysis was made for 2,4-dinitroaniline, 2-chloro-4-nitroaniline, 4-chloro-2nitroaniline, 2,5-dimethoxyaniline, 2-bromo-4-nitroanisole and 2-bromo-5-nitroanisole, transferring the force constants obtained beforehand. The observed and calculated frequencies agree with an average error of 15.8 cm-1. Unambiguous vibrational assignments of in-plane fundamentals of the six molecules have been made and revised assignments are suggested.
