1, 1-二苯基-2-苦基肼、苦基-N-氨基咔巴基样品及其从各种溶剂中重结晶的样品的自旋-自旋和自旋-晶格弛豫时间已确定为 19.3 Mc/sec。发现大多数再结晶样品的自旋晶格弛豫时间增加，并且样品的熔点降低。由于晶格可能发生变化，可以用变量交换相互作用来解释这些结果。 Bloembergen 和 Wang 的三库模型已用于评估自旋交换和交换晶格的弛豫时间。
Spin-spin and spin-lattice relaxation times have been determine at 19.3 Mc/sec for samples of 1, 1-diphenyl-2-picrylhydrazyl, picryl-N-aminocarbazyl, and their recrystallized samples from various solvents. It is found that the spin-lattice relaxation time increases in most of the recrystallized samples and the melting points of the samples decrease. It has been possible to explain these results in terms of variable exchange interaction due to a possible change in lattice. The three-reservoir model of Bloembergen and Wang has been used in order to evaluate the relaxation times for spin to exchange and exchange to lattice.
