Nitrogen pure quadrupole resonance and proton magnetic resonance in the thiourea-cyclohexane inclusion compound. Evidence for phase transitions

Four different phases have been identified in the solid thiourea-cyclohexane inclusion compound in the course of a study of the dependence of the nitrogen pure quadrupole resonance spectrum on temperature. The corresponding transitions can be related to molecular motions. Results of proton magnetic resonance, X-ray diffraction, and micro-differential thermal analysis experiments are presented and an interpretation of the transitions is proposed.
