摘要
本文利用一维多量子Raman磁共振谱线的线宽测定了氯仿(CHCl_3)中碳氢体系的多量子的弛豫时间,由此得到第二类标量耦合弛豫起主导作用时的碳氢核自旋弛豫的交叉相关系数,氯核与碳和氢核的标量耦合常数,以及它们的相对符号。
Multiple Quantum (MQ) relaxation times of carbon-proton spin coupling system in chlo-roform(CHCl3), where the scalar relaxation mechanism of the second kind dominates the relaxation processes, were measured via their relevant MQ line widths in One Dimensional (ID) MQ Raman Magnetic Resonance(RMR). The cross correlation coefficient between carbon and proton spins and their coupling constants to the chlorine spin as well as their relative sign were deduced.
