    Sure, arauca, in some cases the excited electronic state can follow a course other than simply giving up its energy and returning to the ground state as described in this thread. If this involves the breaking and reforming of chemical bonds, that's photochemistry.

    What I find interesting are those cases - such as electrocyclic reactions in organic chemistry - where you get different products depending on whether you use heat or light as the energy input, due to the differences in symmetry of the interaction.
