The nuclear spin relaxation times of the protons in dilute solutions of sodium in liquid ammonia have been measured at 30 Mc/sec over the room temperature‐dry ice range. The data can be interpreted on the basis of an associative equilibrium existing between paramagnetic and diamagnetic solute species. This is in agreement with the results of the conventional magnetic susceptibility measurements. The paramagnetic component of the solutions seems to be about one‐tenth as effective as a cupric ion in inducing nuclear relaxation.
