Femtosecond 2 + 1 Resonance-Enhanced Multiphoton Ionization Spectroscopy of the C-State in Molecular Oxygen

[Image: see text] Coincidence electron-cation imaging is used to characterize the multiphoton ionization of O(2) via the v = 4,5 levels of the 3s((3)Π(g)) Rydberg state. A tunable 100 fs laser beam operating in the 271–263 nm region is found to cause a nonresonant ionization across this wavelength r...

description [Image: see text] Coincidence electron-cation imaging is used to characterize the multiphoton ionization of O(2) via the v = 4,5 levels of the 3s((3)Π(g)) Rydberg state. A tunable 100 fs laser beam operating in the 271–263 nm region is found to cause a nonresonant ionization across this wavelength range, with an additional resonant ionization channel only observed when tuned to the (3)Π(g)(v = 5) level. A distinct 3s → p wave character is observed in the photoelectron angular distribution for the v = 5 channel when on resonance.
