Abstract

Low-frequency vibrational modes of peroxo-bridged high-spin biferric complexes have been observed using nuclear resonance vibrational spectroscopy (NRVS; see picture, PVDOS=partial vibrational density-of-states) and assigned using DFT calculations. Correlations between the spectral features and the structure of peroxo-bridged cores form a basis for structural elucidation of enzyme-peroxo intermediates.
