Abstract
Vibrational energy transport in a short 310-helical peptide is studied by time-resolved femtosecond infrared spectroscopy. The C−D vibrations of decadeuterated leucine incorporated in the helical chain are excited, and the subsequent flow of vibrational energy through the helix is monitored by employing C═O probes at various distances from the heat source as local thermometers. The C−D modes are not resonant to the C═O modes, neither directly nor through any Fermi resonance, thereby suppressing resonant energy transfer directly along
