Abstract
Planar and non-planar force field calculations for o-, m- and p-dicyan obenzenes were carried out using published data on the parent molecule and one isotope in each case. General valence force fields were deter mined using 61 (43 planar and 18 non-planar), 61 (43 planar and 18 non -planar) and 58 (41 planar and 17 non-planar) parameters for the o-, m - end p-isomers respectively. It was found that the earlier proposed a ssignments for some of the wave-numbers need to be revised. (C) 1997 b y John Wiley & Sons, Ltd.
