โœฆ Synopsis

Using the femtosecond Raman-induced polarization spectroscopy (RIPS) technique, we have observed ground vibronic state rotational coherence in gaseous N2, COZ and OZ. Both theoretical and experimental studies are reported. The theory is in excellent agreement with experiment. At earlier pump-probe delays, the time evolution of the polarization recurrence is well described by a rigid rotor model. Higher order spectroscopic constants are extracted from longer delay time spectra. The rotational relaxation constants for ground vibmnic state N2 and 02 are also measured using the real-time technique.

Raman-induced polarization spectroscopy (RIPS) experiments were conducted at room temperature and pressures below 2 atm in pure N 2 and CO 2 . Both homodyne and optically heterodyne detection were used. Calculations of the signal as a function of the pump-probe delay were performed taking into accou

A series of rotational wave packet recurrences originating from single 2-level coherent rotational superpositions are observed in the E(~Eg) state of Li 2. The rotational wave packet is created by ultrafast laser excitation from a specific ro-vibrational level in the A(IEff) state selected by cw las
