Generally used to describe a chemical reaction caused by absorption of @UT07492@, @VT07496@ or @IT07399@ radiation. There are many ground-state reactions, which have photochemical counterparts. Among these are photochemical nitrogen extrusions, photocycloadditions, photodecarbonylations, photodecarboxylations, photoenolizations, @P04614@, photoisomerizations, photooxidations, photorearrangements, photoreductions, photosubstitutions, etc.
Note:
Photochemical paths offer the advantage over thermal methods of forming thermodynamically disfavoured products, overcome large @A00093@ barriers in a short period of time, and allow reactivity otherwise inaccessible by thermal methods.
