Three exponentials are needed to fit the decrease in scattered light intensity with increasing delay time between pump and probe pulses. The decay time of the fastest component varies between 270 and 120 fs if the grating fringe spacing is reduced from 15.5 to 7.8 ,um at constant dye concentration (
