Experimental Observation of Collective Modes of Electron Spin Magnetization Motion in Dilute Solution of 14N Nitroxide Radicals
摘要
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.
