Abstract

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 CHBr₃, 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.
