A NUCLEAR QUADRUPOLE RESONANCE INVESTIGATION OF THE STRUCTURE OF HEXACHLOROBENZENE.

Abstract

Nuclear quadrupole resonance measurements were made at -78C of the asymmetry in the electric field gradient tensors of hexachlorobenzene single crystals. The resultant value of 0.151 = 0.016 at each Cl nucleus supports the double bond hypothesis of asymmetry. A temperature dependence of the NQR signal between -78C and OC is attributed to an increase in the amplitude of the libration of each molecule about its hexad axis with increasing temperature.
