自旋弛豫时间测定是研究固体物质分子动力学性质的有效手段,已广泛应用于植物糖、氨基酸、维生素、肾上腺素以及睾丸激素等多类代谢物分子动力学性质的研究中.近来上述方法也被用于其他代谢物分子动力学性质与其多晶型相变的关系以及对代谢物结构依赖性的研究.该文将在介绍自旋弛豫时间及其测定方法的基础上,着重对自旋弛豫时间测定研究植物糖、氨基酸及其衍生物分子动力学性质的应用工作进行讨论.
Measurement of spin relaxation times is a useful tool for studying molecular dynamics in solids. It has been applied in the studies of molecular motions of sugars, amino acids, vitamins, adrenalin and testosterone, et al. Recently, it is also used in the studies of molecular dynamics associated with polymorphic phase transitions and structural dependence of molecular dynamics in small organic metabolites. This paper gives an introduction of spin relaxation times and their measurements with the emphasis on its application in the studies of molecular dynamics of sugars, amino acids and their derivatives.
