Subpicosecond conformational dynamics of small peptides probed by two-dimensional vibrational spectroscopy.

S Woutersen1, Y Mu, G Stock, P Hamm.   

Abstract

The observation of subpicosecond fluctuations in the conformation of a small peptide in water is demonstrated. We use an experimental method that is specifically sensitive to conformational dynamics taking place on an ultrafast time scale. Complementary molecular-dynamics simulations confirm that the conformational fluctuations exhibit a subpicosecond component, the time scale and amplitude of which agree well with those derived from the experiment.
