Abstract
We report a joined experimental and computational study of Raman and Resonance Raman spectra of amides in aqueous solution. By employing state-of-the-art QM/MM methods combined with synchrotron–based UV Resonance Raman spectroscopy, we propose a protocol to interpret and reliably predict Resonance Raman spectra for amide systems in water, which are prototypical system for the peptide bond. We demonstrate that the main experimental spectral features can be correctly reproduced by simultaneously taking into account the dynamical aspects of the solvation phenomenon, specific solute–solvent hydrogen bond interactions and mutual solute–solvent polarization effects.
