The electronic spectroscopy of protonated indole was investigated experimentally and theoretically. Two isomers have been observed in this experiment. The first isomer corresponds to the lowest energy isomer in the calculations, absorbing at ~350 nm

The very fast relaxation of the excited states to the ground state in DNA/RNA bases is a necessary process to ensure the photostability of DNA and its rate is highly sensitive to the tautomeric form of the bases. Protonation of the bases plays a cruc
