Energy-transfer dynamics of high-pressure rovibrationally excited molecular H2.
The energy-transfer dynamics of high-pressure molecular H(2) gas initially prepared in the |X (1)Sigma(g) (+),v = 1,J = 1 state using stimulated Raman pumping are probed with rotational Raman scattering. A computer simulation that incorporates the effects of collision-induced vibrational energy transfer is described and used to fit the experimental Raman scattering results obtained as a function of the pump/probe delay time. The 4.78 x 10(-14) +/- 3.85 x 10(-16) cm(3) s(-1) molecule(-1) vibrational energy-transfer rate for decay from the |X (1)Sigma(g) (+),v = 1,J = 1 >state compares well with other lower-pressure studies.
