Abstract
The 14N nuclear quadrupole resonance spectrum of cubic tetracyanoethylene was found. The temperature dependence was determined between 77.3 K and room temperature. The transition temperature between the cubic and the monoclinic phase was found to be 292.0±0.5 K. The values of eqQ and η for both phases are discussed considering the contributions of the crystalline electric field and the existence of specific intermolecular interactions.Keywords
