## Abstract ^13^C NMR spinโlattice relaxation times (__T__~1~) and nuclear Overhauser enhancements (ฮท) were measured for dithiarsolanes. The contributions of dipolar (__T__) and spinโrotation (__T__) mechanisms were determined. The __T__~1~ data were analysed to obtain information on the relative o
Relaxation calculations for rapidly spinning samples show that spin-lattice relaxation time (T 1Z ) anisotropy varies with the angle between the rotor spinning axis and the external field. When the rate of molecular motion is in the extreme narrowing limit, the measurement of T 1Z anisotropies for t
