Abstrac~Analyses of the rotational diffusion characters of free and bonded nitroxyt radicals in polyvinylacetate were carried out. The radical rotational character essentially depends on the molecular sizes of the radicals. The movement of the "small" radical is matched by the arbitrary jump tumblin

β¦ Synopsis
A method of "additional broadening" is proposed that permits the measuring, with a minimal error, of rotational correlation times together with the degree of anisotropic rotation (DAR) of nonspheroidal organic nitroxyl radicals in the rapid motion rqion, in isotropic media. Using this method, it is demonstrated for two solutions of the same radical that DAR is temperature independent, in contrast to previously published data.
