摘要: 本文提出了分离偶极-偶极驰豫的新方法参数分离法。对于稳固的刚性分子,可以通过仲碳和叔碳弛豫时间的测量算出扩散系数,这不仅可以用于研究分子的动态特性。还可以用于计算季碳的偶极-偶极弛豫。文中报道了睾丸甾酮丙酸酯驰豫的研究结果,表明参数分离法可对季碳的驰豫机制进行有效的研究。

Abstract: In this paper, a new method was suggested to separate Dipole-Dipole relaxation, that is called parameter separation method. For a stable rigid molecule, the diffusion coefficient could be calculated from measurement values of secondry and tertiary carbons, which is usually not only for a kinematic research, but also for evaluation of Dipole-Dipole relaxation of quaternary carbons. This procedure shows higher reliability. The result of relaxation study on title mentioned compound shows that parameter separation method is quite efficient for the study of relaxation mechanism for a stable rigid molecule, especially for quaternary carbons.
