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.
