Electronic Paramagnetic Relaxation Times in Potassiumhyphen;Ammonia and Potassiumhyphen;Deuteroammonia Solutions

摘要

The longitudinal and transverse paramagnetic relaxation timesT1andT2for Ksngbnd;NH3and Khyphen;ND3solutions, have been measured over a range of concentrations and temperatures.T1is found to be equal toT2at the higher concentrations. At the lower concentrations, the values ofT1are found to be greater than those ofT2, although at the very lowest concentrations studied they are again approaching each other in value with decreasing molarity. The product of the linewidth at zero rf field by the ratio of temperature to viscosity is found to be constant in both NH3and ND3over the temperature range studied.
