摘要	By taking into account the effect of variation in angular wavefunction, reconsidering the expressions of spin-orbit coupling parameters, diagonalizing the complete d(3) energy matrix in a trigonally distorted cubic-field and using the wavefunctions from it, the unified calculations of the energy spectrum and EPR spectrum for ruby and their pressure-induced shifts have been carried out. All the calculated results are in very good agreement with a lot of experimental data. The estimation by making use of superposition model has also demonstrated the high sensitivity of trigonal-field parameters to angular variation. 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.
