Abstract

Information about $^{14}N$ relaxation rates is obtained for thioacetamide (TA) in acetone from a detailed line-shape analysis of the $^1H$ resonance signal of $NH_2$ group. The effect of pressure and of temperature were investigated, and activation energies for molecular reorientation are given. And also $^1H$ relaxation rates of $NH_2$ group of TA as a function of pressure and temperature are obtained. These results are discussed with the results for the $^{14}N$ relaxation of amine group.

티오아세트아미드/아세톤 용액에 대한 $^{14}N$ 이완속도를 $NH_2$기의 $^1H$ 공명 신호의 자세한 선모양분석으로부터 구하였다. 압력과 온도의 효과를 조사하고 분자 재배향의 활성화에너지를 구하였다. $NH_2$기의 $^1H$ 이온속도도 압력과 온도의 함수로 구하였다. 이들 결과를 아민기의 $^{14}N$ 이완의 결과와 함께 고찰하였다.
