Structural relaxation in the peptide model N-methylacetamide (NMA) is studied experimentally by ultrafast optical Kerr effect spectroscopy over the normal-liquid temperature range and compared to the relaxation measured in water at room temperature. It is seen that in both hydrogen-bonding liquids, relaxation is present, and in each case, it is found that this can be described by the Cole–Cole function. For NMA in this temperature range, the and relaxations are each found to have an Arr...
