Abstract

Recently, Salikhov formulated a new paradigm of spin exchange. The basic statement of this paradigm is that due to the spin coherence transfer from the interaction partner in course of random bimolecular collisions of paramagnetic particles collective modes of electron spin magnetization motion in dilute solutions are formed. Here are presented some peculiar features in the concentration dependence of the EPR spectrum shape of ¹⁴N nitroxide radicals solution. Experimental results are in a good agreement with theoretical predictions of the new paradigm of spin exchange and its manifestations in EPR spectroscopy.

14N氮氧化物自由基稀溶液中电子自旋磁化运动集体模式的实验观察

最近，Salikhov提出了一种新的自旋交换范式。该范式的基本陈述是，顺磁粒子在随机双分子碰撞过程中，由于相互作用伙伴的自旋相干性转移，形成了稀溶液中电子自旋磁化运动的集体模式。本文介绍了14N氮氧化物自由基溶液EPR谱形状随浓度变化的一些特殊特征。实验结果与自旋交换新范式的理论预测及其在EPR光谱中的表现相吻合。
