The heterocyclic nitrogen containing molecules, e.g. pyrrole and imidazole, represent important building blocks in many biomolecules fulfilling important functions in living organisms. Radiation damage of these molecules (by UV photons or electrons) can threaten functioning of these biomolecules. In order to understand the photostability of these rather complex species at a detailed molecular level, we have to investigate the photochemistry of their simpler constituents, namely of the UV chromophores such as the heterocyclic compounds studied here.
