Electric field effects in magnetic resonance. Part II. 35Cl quadrupole resonance frequencies

Abstract

The ³⁵Cl nuclear quadrupole resonance frequencies of some 3-chloroacetylacetonato-complexes are shown to vary markedly according to the polarity or charge of the complex, and to depend very little on the nature of the central element. The differences can be explained in terms of linear intramolecular electric-field shifts and their signs and magnitudes correlate with experimental values of the Stark effect coefficients for ³⁵Cl attached to carbon.
