Temperature dependence of the ³⁵Cl nuclear quadrupole resonance frequencies of the trimeric and tetrameric phosphonitrilic chlorides

Abstract

The 35 Cl nuclear quadrupole resonance frequencies of the trimeric and tetrameric phosphonitrilic chlorides have been studied as a function of temperature. Two forms of the tetramer were used and the differences in their spectra ascribed to crystallographic effects. Correlation of each of the lines in the trimer to a set of chlorine atoms in the unit cell were attempted using crystallographic data.
