Abstract
The nature of the displacement of the frequency of a characteristic vibration under the influence of the nonbonded interactions of atoms within a molecule (the “field effect”) has been studied. It has been shown in the example of the interaction of the bonds in the tetratomic Cl-C-C=O fragment that the Ν(C=O) frequency increases under the influence of the dipole-dipole interaction of the C=O and C-Cl bonds; the same interaction causes a decrease in the freqency, if the Cl atom is replaced by an electropositive atom. The physical meaning which should be imparted to the Urey-Bradley potential, in particular, follows from the analysis presented.
