Abstract
Dynamics of two proteins [myoglobin and photoactive yellow protein (PYP)] i nitiated by photoexcitation were studied by the time-resolved transient gra ting (TG) and photoacoustic methods. For both proteins, the temporal profil es of the TG signals showed new features that have not been detected before by the transient absorption method. These dynamics were attributed to the volume change, which is caused by the protein dynamics apart from the chrom ophores.
