✦ Synopsis

With ultrashort pulses of less than 100 fs it is possible to excite coherently several vibrational modes of polyatomic molecules simultaneously. The femtosecond time resolution of the experiment allows the study of pronounced high-frequency beat phenomena up to 10 THz. The frequency difference between vibrational modes separated by more than 300 cm-' may be determined with high precision.

Molecular quantum beats are observed in the isotropic fluorescence decay following laser excitation of individual rotational states of CzNz via the vibronically allowed 4; A ( 'C; ) +g ( 'Cl ) transition near 2 19 nm. Strong quantum beats occur with selective excitation, by both P-and R-branch trans

A new class of detuning oscillations in the terahertz domain is reported in (nanosecond) coherent Raman scattering spectroscopies with incoherent light. Vibrational dephasing rates are precisely measured in neat benzene, benzene-d, and in their binary mixture where Bohr frequency difference beats ar
