本文论证了化学交换和弛豫之间存在的相似之处，并提出可以用完全类似于最近为研究化学交换而引入的双共振法来研究弛豫过程。给出了相互作用自旋纵向磁化强度随时间变化的所罗门方程的重新推导，得出了驰豫时间与不同自旋相对丰度的关系。给出了甲酸和乙醛样品的实验结果。
An exposition is given to demonstrate the close analogies that exist between chemical exchange and relaxation, and it is suggested that relaxation processes may be investigated by a procedure completely analogous to the double‐resonance method recently introduced for the study of chemical exchange. A rederivation of the Solomon equations for the time dependence of the longitudinal magnetizations of interacting spins which brings out the dependence of the relaxation times on the relative abundance of the different spins is given. Experimental results on samples of formic acid and acetaldehyde are presented.
