✦ Synopsis


A distributed model for the response of the electric field gradient at a nucleus to perturbation by external fields is proposed, and an implementation using perturbation of distributed multipole moments by a test nuclear quadrupole is described. Calculations on the HC1 and Cl2 molecules show the response of the electric field gradient at Cl to be dominated by induced c charge flow. Application to hydrogen-bonded complexes of HCl gives a qualitative explanation of 35C1 quadrupole coupling constants in B...HCl where B is a base such as H3N, HCN, CH3CN, H3P and OC.
