The nucleobases that are involved in replication exhibit short excited-state lifetimes which provide high intrinsic stability against otherwise harmful UV photo-damage. UV protection comes about when electronic excitation is converted to heat by internal conversion at rates too fast for other more harmful reactive pathways to occur while subsequently safely dissipating the energy to the environment. The canonical nucleobases generally decay in less than 1 ps, orders of magnitude faster than in most other heterocyclic compounds This property would have been highly advantageous for the first self-replicating mols. in prebiotic times before modern enzymic repair or the formation of the ozone layer that would later attenuate the high levels of UV radiation penetrating the early atm. The safe elimination of excess electronic energy in the canonical bases is exquisitely sensitive to mol. structure and much slower relaxation is observed in many closely related structures. These many variations of the canonical nucleobases, such as different derivatives and analogs, would likely have been present in a primordial soup. Alternative combinations of mol. building blocks would conceivably have been possible to for.
