• 論文の詳細を見る

• The proton spin-lattice relaxation rate 1 /T. in solid thioacetamide were meas-ured between 28.5K and 200K at two Larmor frequencies, Il.4MHz and25 MHz. The temperature dependence of 1/T3 was characterized by tlu'ee maxima,two maxima observed around 90 K and 37 K showing the frequency dependenceand the frequency independent one at 44 K. Taking into account two crystal-Iographically inequivalent thioacetamide molecules, the temperature and Larmorfrequency dependence of 1 /T. was explained by the contribution from the quantummechanical and classical limit of tunneling rotation of the methyl groups aroundtheir C. 3xeS.
