• The L.,. absorption spectra of the metal tons in layered 3d transition-metalthiophosphates MPS. (M=Mn, Fe, Ni) have been measured. Results are dis-cussed by comparing with the spectra of other transition-metal compounds andwith the theoretical calculation by Gupta and Son. The spectra are interpretedin terms of the multiplet structure which results from the interaction between a2p hole and 3d electrons of a localized metal ion. Since the p-d interaction isreduced by the delocalization of metal 3d orbitals, the mtrltiplet structure be-comes inconspicuous as covalency is increased. It is concluded that the near-edgestructure of the metal L.,. absorption spectrum of an ionic 3d transition-metalcompound exhibits the multiplet structure, while that of a covalent compoundrepresents the projected density of states of the conduction band.
