The diffracted signal from a thermal grating formed by radiationless processes is proposed as a method for measuring energy deposition quantum yields. The deposition quantum yield a few ns after pumping of iron(lI1) tetraphenylporphyrin chloride is found to be O-93*0.07 using this new technique.

The rotational diffusion time of ruthenium( II)-bis( 2,2'-bipyridine) (2,2'-biquinoleine) has been measured in polar solvents of different viscosity. The rotational dynamics can be explained in terms of the Stokes-Einstein-Debye hydrodynamics theory under stick boundary condition by considering the
Transient gratir~ optical Kerr e&t measurements in the isotropic pbase of the nematic liquid crystal pentylcyanobiphenyl (5CB) are presented. Subpicosecond time resolution permits the first direct investigation of the time correlation function for the local mokcular dynamics of the molecules within
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 (
