From theoretical analyses and calculations, it has been confirmed that the local strains around Cr〓 in SrTiO〓: Cr〓 are about twice the bulk ones. It is found that the change of Dq〓 with pressure makes main contribution to PS of ground-state g factor of SrTiO〓: Cr〓. It is the admixtures of basic wave functions that cause the strain-induced splittings of t〓E and t〓A〓 levels of SrTiO〓: Cr〓. It is found that there are non-vanishing matrix elements of operators C , C and C between wave functions with positive M〓 and those with negative M〓 and the shortcomings in previous literature have been overcome.
