Abstract

The CNDO/2 force method is applied to the study of the in-plane force field of benzene. Although, as usual, the direct calculated values differ significantly from the true ones, after scaling them with altogether 3 empirical parameters, the complete set of 26 force constants as well as the vibrational frequencies of C6H6, C6D6 and sym C6,H3D3 are well reproduced. The force field obtained seems reliable enough even to allow critical judgement of the experimental results.
