Abstract

Pulsed nuclear magnetic resonance experiments on protons in solid hydrogen sulfide have been carried out at 10 Mc/sec over the temperature range of 4.2° to 175°K. Proton spin—lattice relaxation times T1 and T1r along the static and rotating magnetic fields, respectively, and free‐induction‐decay shapes were measured. The T1r‐vs‐reciprocal‐temperature curves exhibit several minima which, together with the slopes, allow the determination of the correlation times of the molecular motions as a function of temperature. From the free‐induction‐decay shapes were derived the intermolecular and intramolecular contributions to the second moment of the proton‐resonance line shape. The temperature dependence of the second moment gives information about the molecular motions and the structure of solid hydrogen sulfide. Models of the structure and motion are proposed and examined.
