Potential function of internal rotation of (CH3)2CClNO,CH3CCl2NO,and their deuterium analogs

The potential function has been constructed for internal rotation of the NO-group in (CH₃)₂CClNO, CH₃CCl₂NO, and their deuterium analogs. It has been established that the N=O bond in the cis_Cl conformer of CH₃CCl₂NO does not eclipse the C-Cl bond, rather forming an angle of approximately 30. It has been shown that a change in substitutent on the -carbon atom may produce a substantial change in the form of the potential function of internal rotation (PFIR) of the NO group.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 550–555, March, 1990.
