A comparison of calculated and measured hyperfine structure of epr spectra of Mn2+ ion in LiNbO3 monocrystal

An outline of numerical calculation of positions and intensities of spectral lines in EPR spectra of Mn²⁺ ion in LiNbO₃ is presented. Results of numerical calculations obtained by means of computers TESLA 200 and SIEMENS 4004 are compared with experimental spectra. A modification of Jacobi's method of diagonalization is described, which was used for exact solution of a secular equation with Hermitian matrix.
