Abstract
The longitudinal and transverse paramagnetic relaxation times T1 and T2 for K–NH3 and K‐ND3 solutions, have been measured over a range of concentrations and temperatures. T1 is found to be equal to T2 at the higher concentrations. At the lower concentrations, the values of T1 are found to be greater than those of T2, 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 NH3 and ND3 over the temperature range studied.
