The deuteration rates (D-rates) of H.P0.- radicals (R.) in partially deuteratedNH.H.PO. crystals are measured by ESR of Sea: doped in the crystals. It is foundthat the phase transition temperatures ( T.) of the crystals depend linearly on 7<.; T.(R.)= 148-X-94R. [K]. Using this relation and data about total D-rate of highlydeuterated ADP obtained by others, D-rates of NHj radicals (7?.) in the crystals arecalculated. It is pointed out that the shift of T. does not depend on 7?. but on 7?..
