  abstract = {We show here that the temperature dependence of the amide I band of myoglobin shows evidence for a low-lying S-elf-trapped state at 6.15 mum. We have conducted a careful set of picosecond pump-probe experiments providing results as a function of temperature. and wavelength and show that this low-lying state has a 30 ps lifetime at 50 K, much longer than the relaxation time of the main amide I band at 50 K. Fits of the temperature dependence of thermal occupation of this state yield the result that it lies 280 K below the main amide I band. Since the gap energy of this state is approximately equal to room temperature, this self-trapped state can act as a transient store of vibrational energy at physiological temperatures in biomolecules and can help to direct the path of energy flow in a biomolecule under biological conditions.
