摘要：

Optical transition between 3d bands in cubic MnO and MnS is measured upon applying hydrostatic pressure. Pressure dependence of the Racah parameter B and the crystal field strength Dq is determined. The pressure coefficients of transition energies from (6)A(1) to T-4(1) and T-4(2) states calculated using the Sugano-Tanabe diagram agree well with experimental values. An emission band at 1.63 eV in MnS at 1.5 K is identified to be T-4(1) --> (6)A(1) transition accompanied by a large lattice relaxation.
