COMPUTER MODELING OF ANISOTROPIC ESR SPECTRA WITH A HYPERFINE STRUCTURE

Abstract

The method for computer simulation of ESR spectra with an anisotropic g-factor and hyperfine structure (HFS) is described. The calculation program takes into account the dependence of the width of individual resonance absorption lines on the magnetic quantum number mI and on the angular orientation of the axes of the paramagnetic complex symmetry in the magnetic field. The efficiency of the method is demonstrated by the example of modeling ESR spectra of V4+ and Cu2+ ions in oxide glasses.
