Ultrafast polarization and vibrational motions in bacteriorhodopsin studied by coherent infrared emission spectroscopy

Abstract : The primary events in bacteriorhodopsin are investigated by coherent infrared emission spectroscopy of oriented purple membranes. Long-lived vibrational motions involving charge displacements are observed following sudden (<11 fs) macroscopic membrane polarization appearing upon visible excitation.
