Abstract.
Resonant infrared femtosecond light pulses in the 3 μm region are used to excite specific CH-stretching modes of liquid 1,1,1-trichloroethane, cyclopentane, and cyclohexane. The ultrafast redistribution of vibrational excitation between different CH-stretching modes and the vibrational relaxation of these modes are monitored by spontaneous anti-Stokes Raman scattering of properly delayed and spectrally shaped probe pulses. The results are treated with a rate-equation system, yielding energy-redistribution and energy-relaxation times.
