摘要：

From recently published experimental frequencies and new Raman data obtained for FeS2 marcasite, the complete valence force fields of FeS2, RuS2 pyrite-type and FeS2 marcasite compounds were computed. Values of the main force constants and of the principal potential energy distributions are discussed and compared with literature data with particular emphasis on the relative M-S and S-S bondings in these MS2 phases.
