Abstract
Pulsed, supersonic molecular beams and pulsed lasers are particularly well matched tools when combined
in molecular reaction dynamics studies. Salient features of an experiment using two pulsed molecular
beam sources, a pulsed ultra-violet laser for creating reactive atoms by laser ablation and a pulsed dye
laser for performing laser-induced fluorescence detection of the products are described. Differences with
steady-state molecular beam experiments are outlined with respect to the following points: facility of
inverting the data, possibility of obtaining high signal-to-background ratios and wide ranges of collision
energy. These points are illustrated with some results concerning the reactions:
