    Raman scattering of single-crystal RuTe2 has been carried out with good frequency resolution and wide wavelength coverage. In this article, our results are presented and compared with those for other ruthenium dichalcogenides (RuSe2, and RuS2) reported previously. We found a good linear relationship between all Raman shifts and the reciprocal chalcogen mass. We also observed resonant scattering related to inter-electronic-band transitions.

    Raman scattering of mixed dichalcogenides FexRu1-xS2 has been measured for the first time. Our results show not only resonant enhancements that are related to the inter-electronic-band transitions, but also mixed mode behavior with strong coupling between neighboring Raman active modes. Good interpretation is obtained by the spa tial correlation model.

    The Raman spectra of the mixed RuSxSe2-x crystal systems have been measured for the first time. As the composition parameter x becomes 1.8 and 0.6, both the E(g) and the A(g) modes of pure crystals merge into the RuS2-like and the RuSe2-like-modes, respectively, in the mixed pyrite. The broadenings and shifts are significant for x range between 0.6 and 1.8. These unique features are different from the so called "one-mode" and "two-mode" behaviours of some II-VI, III-V compound alloys. Our results are interpreted in terms of the spatial correlation model.
