Abstract
Coherent vibrational dynamics in a mutant of the green fluorescent protein are studied by diffractive optic ultrafast transient grating spectroscopy. Two low frequency <100 cm−1 modes are observed. We propose that one at 95 cm−1may be associated with intramolecular torsional motion in the excited state. The possible importance of such modes in understanding the very high quantum yield of the intact GFP is discussed.
