Optical-detection ESR tomography of short-lived ion-radical pairs in a radiation track
Odintsov B. M. , Yakhin R. G.
The method of optical detection of ESR has been used for an ESR-tomography study of irregularities in the spatial distribution of short-lived paramagnetic centers in a radiation track. Samples of polystyrene with a 1CP3 Μ admixture of paraterphenyl-i/14 were used as models. It was shown with their help that optical detection raises the sensitivity of conventional ESR tomography by three or more orders of magnitude, and it expands the capabilities of the method in a fundamental way in research on new classes of compounds. The results show that the method of optical-detection ESR tomography proposed here makes it possible to carry out studies in the space of irregularities of short-lived ion-radical states. These states are crucial to fast solid-state chemical reactions which are of fundamental importance.
