Similarly, for other topics, whether they be group transfer reactions, salvation dynamics, reaction coordinates, semiclassical mechanics, or others, I have been influenced to varying degrees by several factors -- recognition, sometimes accidental, of a puzzling problem in experiments, a sometimes non-existent or more frequently an inadequate explanation of the results; by making as useful an analysis of the mechanism as I could at the molecular level, and devising a way, utilizing a little physics and mathematics, of implementing the physical ideas, I could work towards some relatively simple-looking equation to describe the result.
