Infrared and Raman spectra of Fe-4(S/Se)(4) Clusters with terminal halide ligands and MoFe3S4 clusters with terminal thiolate and halide ligands are presented and interpreted on the basis of the force fields determined in the accompanying paper. The Raman spectra of halide coordinated Fe-4(S/Se)(4) clusters are characterized by the fact that vibrations of the terminal ligands appear with little or vanishing intensity. Infrared and Raman spectra of MoFe3S4 clusters with terminal thiolates are correlated to those of corresponding Fe4S4 systems, which were investigated in part 1 of this study and interpreted with normal coordinate analysis. Band assignments are checked by employing MoFeS4 clusters with terminal halide ligands. Spectra of these systems are in turn compared to those of their Fe4S4 counterparts, i.e., Fe-S cubane clusters with chloro, bromo, and iodo ligands. A consistent interpretation of all spectra is presented. General implications of these results are discussed.
