ResumoAbstract Using Raman, terahertz (THz), and mid-infrared (IR) spectroscopies, the vibrational spectra of two chromophore models of hydrogen-producing [FeFe]-hydrogenase, Fe 2 (μ-S 2 C 3 H 6 )(CO) 6 and Fe 2 (μ-S 2 C 2 H 4 )(CO) 6 , have been assigned. The combination of absorption and scattering techniques, along with DFT calculations, allows for assignments to be made without traditional isotopic substitution methods.
