2. Dual-frequency 2D-IR spectroscopy heterodyned photon echo of the peptide bond
The structure fluctuations of the peptide bond interacting with solvent are examined through the coupling and correlations of the frequency distributions of amide I and amide II transitions. The fluctuations of the two modes are anticorrelated as a result of the solvent-induced changes in the mixing of the dominant valence-bond structures of the peptide. Sig

3. Primary intermediate in the reaction of oxygen with fully reduced cytochrome c oxidase.
The primary intermediate in the reaction of oxygen with cytochrome c oxidase was generated by photodissociating carbon monoxide in a continuous flow rapid mixing apparatus. The presence of the primary intermediate was confirmed by a comparison of the iron-dioxygen stretching frequency with that obtained in the reaction of oxygen with the mixed-valence enzyme

4. Normal coordinate analysis of the copper center of azurin and the assignment of its resonance Raman spectrum.
Normal coordinate analysis that utilizes a general valence force field and the Wilson FG matrix method has been applied to several structural models representing the active site of the blue copper protein, azurin. The models included tetrahedral and square planar CuN2SS', trigonal CuN2S, and trigonal bipyramidal CuN2SS'O structures in which the Ns are imidaz
