Samuel Leutwyler - Cytosines: Excited-State Lifetimes, Nonradiative Decay Mechanism and Water Clusters

Photophysical investigations of the canonical nucleobases that make up DNA and RNA show that in room-temperature solvents, their excited states decay with (sub)picosecond lifetimes (τ = 0.3–2 ps). The apparent generality of ultrafast excited-state deactivation in the canonical nucleobases has led to the hypothesis that nucleobases are molecular survivors of the harsh UV environment on the early Earth before the emergence of life.
