State‐to‐state reaction dynamics

NOV 01, 1980

Tunable lasers facilitate the finding of relative probabilities for forming product molecules in specified quantum states from reagents in selected states, a long‐standing objective in chemical dynamics.

The study of chemical reaction kinetics can be likened to the task of making a motion picture of a reaction. The trouble thus far with achieving this goal seems to be the problem of too many would‐be actors who strut upon the stage without proper cue and mumble their lines too rapidly to be understood—for chemical reactions occur with the ease of striking a match and at a speed so fast (on a subpicosecond time scale for the making of new bonds and breaking of old ones) as to be a severe challenge to the moviemaker who would like to record individual frames.
