✦ Synopsis

Using independently tunable pump and probe pulses in the infrared, time-and frequency-resolved spectroscopy of vibrationally excited, polyatomic molecules in liquids is demonstrated for the first time. Experimental data are presented for CHBr,, measuring the population lifetime via excited-state absorption of the CH-stretching mode; for larger probe delay, the non-equilibrium population of intermediate vibrational levels in the relaxation ladder of bromoform is observed.

Intramolecular proton transfer in the excited electronic state of 2-(2-hydroxyphenyl)-benzothiaxole (HBT) is investigated on the picosecond time scale. A Stokes shift of approximately 10000 cm-' between the absorption and the fluorescence maximum and a fluorescence quantum yield of 1.5% are found fo

A two-pulse method of rapid laser induced isomerization of a triatomic molecule is proposed. One laser pulse is resonant with the bending vibration while the second pulse has its frequency close to the stretch mode frequency. Alternatively the second frequency can be set equal to the second harmonic
