摘要：

Optical study of trivalent 3d transition metal oxide compounds LaSrMO(4) (M=Cr, Mn, Fe and Co) with layered perovskite structure has revealed fundamental features of their electronic structures. Systematic change of the charge-transfer gap (E(gap)) with the 3d element (M) can be explained by a simple ionic model. The spectrum below similar to 7 eV is found to be strongly M-dependent, and is interpreted in terms of multiplet splitting of the final 3d(N+1) state.
