✦ Synopsis

A hybrid quantum/semiclassical simulation method is applied to the photodissociation dynamics of HCI in the Ar-HCI cluster. The method treats the hydrogen quantum mechanically, and the heavy atoms by semiclassical wavepackets. The dynamics of the H atoms if found to show resonances where the H atom rattles between the Ar and Cl atoms before leaving. Particularly interesting is the kinetic energy distribution of the H atom which shows a structure ofpronounced peaks, associated with the resonance levels, while the absorption spectrum is structureless. The dynamics of the process is discussed.

We observed optical saturation curves of the Na(SP) level in cool (T -1700K) premixed laminar H2-O2-Ar flames at 1 atm and in a wide range of fuel/oxidant ratios below as well as above stoichiometry. A pulsed dye laser (pulse duration of 1.2 /~s) was tuned at the upper doublet component. For this re
