Intermolecular interaction of antimony trichloride in the crystal of the bimolecular menshutkin complex with diphenylamine

The relationship between the change in the constants of intra- and intermolecular force fields of the molecules at the gas-crystal transition is discussed. Raman spectra of the crystal of bimolecular complex (C 6 H 5 ) 2 NH.2SbCl 3 at 293 and 77 K are obtained. Theoretical group and normal coordinate analysis of vibrations in the complex are performed.
