Abstract
The reorientational mobility of Mn(II) complexes in diethylphosphoric acid has been studied by ESR over a broad temperature range. An analysis of the spectra has been carried out on the basis of a theory of line shapes developed for Mn(II) ions (S=5/2, I=5/2) under the condition Ω0Τc≫ 1. It has been established that the widths of the hyperfine components of the spectrum of Mn(II) depend on the square of the nuclear magnetic quantum number even in the case of very slow molecular re-orientation, in which the spectrum is complicated by fine-structure effects that are not completely averaged.
