The theoretical treatment of photo-excitation processes is a field for the specialist, and is beyond the scope of this book. The complexity both of the physical concepts, and of the structures of some photochemical transformation products, has tended in the past to frighten many organic chemists into regarding photochemistry as a field outside the range of ordinary mechanistic interpretation, but the last few years have seen the successful application of normal mechanistic principles to excited molecules [i].
