Electronic spectroscopy of DNA bases in the gas phase provides detailed information about the electronic excitation, which places the molecule in the Franck-Condon region in the excited state and thus prepares the starting conditions for excited-state dynamics. Double resonance or hole-burning spectroscopy in the gas phase can provide such information with isomer specificity, probing the starting potential energy landscape as a function of tautomeric form, isomeric structure, or hydrogen bonded or stacked cluster structure. Action spectroscopy, such REMPI, can be affected by excited-state lifetimes.
