- 論文の詳細を見る
Proton spin-lattice relaxation times T. and T., in partially deuterated ammoniumsulfate were measured between 357 K and 118 K. The minimum values of T.,(2N4 sec) in the paraelectric phase were attributed to the random modulationof the dipolar interaction between the protons in NHDf and the naturalabundance of the "O (0.037'3) in SO.". The activation energy E.t-4.1 kcal/molfor the reorientation of S0j' was determined.
