| 中文摘要 | By taking into account the effect of variation in angular wavefunction, by reconsidering the expressions of spin-orbit coupling parameters, by diagonalizing the complete d(3) energy matrix in a trigonally distorted cubic-field and using the wavefunctions from it, the unified calculation of the whole energy spectrum and EPR spectrum for ruby and their pressure-induced shifts was carried out. All the calculated results are in very good agreement with a lot of the optical and EPR experimental data. The estimation by use of superposition model has also demonstrated the reality of calculated results and the high sensitivity of trigonal-field parameters to angular variation. The rates of change of levels with respect to various parameters, the variations of parameters with pressure and the contributions to levels from various parameters were calculated. The distinct differences in magnitude and/or sign of pressure-induced shifts of various levels are immediately determined by their characteristic dependencies on the parameters of interactions. The pressure-induced shifts of levels and g factors have provided important criteria for the correctness of calculations and assignments of the energy spectrum and wavefunctions.
