β¦ Synopsis
The characteristic time for vibrational rclasation in an optically excited molecular electronic state has been measured with picosecond resolution for the molecules rhodamine B and rhodam';\e 6G in solution using a new experimentat technique.

Direct measurements of statespecific vibrational self-relaxation rates for highly excited HCN are reported at energy contents which range between 6500-10000 cm-'. By combining single photon overtone vibration excitation with a laser-induced fluorescence probe of the vibrationally energized species t
The bleaching dynamics of organic dye molecules in solution have been investigated using 70 fs pulses from a colliding pulse mode-locked ring dye Laser. In addition to ground state relaxation on a nanosecond time scale, a fast partid recovery 1s observed. For the dyes Nile blue, oxazine 720, cresyl
A new method, femtosecond time-resolved stimulated emission pumping fluorescence depletion (FS TR SEP FD), has been developed to study the vibrational relaxation of electronic excited states of molecules. Two relaxation rates of dye molecules in different solvents have been observed: (i) the intramo
