Abstract

Using Raman, terahertz (THz), and mid-infrared (IR) spectroscopies, the vibrational spectra of two chromophore models of hydrogen-producing [FeFe]-hydrogenase, Fe₂(μ-S₂C₃H ₆)(CO)₆ and Fe₂(μ-S₂C ₂H₄)(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.
