Av. Burenin, VIRTUAL GEOMETRICAL SYMMETRY GROUP OF A NONRIGID MOLECULE WITH ENERGETICALLY NONEQUIVALENT EQUILIBRIUM-CONFIGURATIONS, Journal of structural chemistry, 37(3), 1996, pp. 377-383
The notion of a virtual geometrical symmetry group of a nonrigid molec
ule with energetically nonequivalent equilibrium configurations is int
roduced. Due to this, methods of qualitative analysis of intramolecula
r effects for such molecules using the concept of symmetry group chain
s are significantly generalized.
