Abstract:
Experimental data obtained in recent years on the electron paramagnetic resonance (EPR) of free radicals in the two-millimetre wavelength range are surveyed. It is shown that measurement of the spectra in this range makes it possible to increase greatly the amount of information derivable by the EPR method and its absolute sensitivity. The results of measurements of the magnetic resonance parameters of nitroxy-radicals, nitroxy-biradicals, and peroxy-radicals as well as data on the molecular mobilities of the above radicals in various matrices are presented. The bibliography includes 62 references.
