Misassignment of the strong Raman band near 1000 cm−1 in some substituted benzenes, and the Herzberg versus Wilson convention for numbering the vibrations of benzene

Abstract

AbstractMono, 1,3, 5‐substituted benzenes (and only these) have a very strong, highly poarized Raman band at 1000±10 cm−1. It is often misassigned as the symmetrical ring breathing, whereas in fact it is derived from the benzene trigonal ring deformation v6. In the current literature the vibrations of benzene are numbered according to either the Herzberg or the Wilson scheme. A plea is made for using only one convention, and reasons are gigen for choosing Herzberg's.
