35Cl NQR spectra, structure, and mutual influence of substituents in the series of chlorine-containing organic compounds of pentavalent phosphorus

Regularities of transmission of the effect of equatorial and axial substituents were established for a number of chlorine-containing organic compounds of pentavalent phosphorus using Cl-35 NQR spectra. The field constants of Cl-35 NQR frequencies of the chlorine atoms participating in the P-Cl bond were estimated for a series of tetrahedral phosphorus ions. The Cl-35 NQR frequencies of chlorine atoms in tetracoordinated ions of pentavalent phosphorus and in analogous isoelectronic silicon compounds are related by a linear dependence.
