The excited-state dynamics of phenol following ultraviolet (UV) irradiation have received considerable interest in recent years, most notably because they can provide a model for understanding the UV-induced dynamics of the aromatic amino acid tyrosi

The role of ultraviolet photoresistance in many biomolecules (e.g., DNA bases and amino acids) has been extensively researched in recent years. This behavior has largely been attributed to the participation of dissociative (1)πσ* states localized a

One of the key questions underlying adenine’s photochemistry following 266 nm excitation is whether or not the dissociative 1 πσ ∗ state plays an active role in the ensuing dynamics. This work describes how laser fluence studies on the Ad + and
