Dn. Singh et al., FORCE-FIELDS FOR C-N-SUBSTITUTED BENZENES .2. PLANAR AND NONPLANAR MODES OF THE 3 ISOMERIC DICYANOBENZENES, Journal of Raman spectroscopy, 28(5), 1997, pp. 355-362
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
