Аннотация:High-spin intermediates with S = 2 generated by gamma-radiolysis of triazidopyridines at 77 K were studied using the ESR method in the X range. Their thermal stability at 77-240 K with the transition to the one-electron states (S = 1/2) due to intermolecular reactions at 100-200 K was shown. The study of saturation processes elucidated an effect of a sharp nonlinear increase in the intensity of the ESR signals from quintet dinitrenes with an increase in the microwave field power higher than 10 mW. This effect can be applied as a method of identification of high-spin molecules obtained together with other paramagnetic products of low multiplicity and in the search for systems with molecular magnetism. A set of principles was developed for making compact undulators based on static molecular magnetic structures using dynamic effects upon the interaction of an electron beam with a laser pulse counter.
