Photoionization of DABCO via high vibrational levels of the S{sub 1} state.

· Chem. Phys. Lett.
The photoelectron spectrum following resonant two-photon ionization of 1,4-diazabicyclo[2.2.2]octane (DABCO) was recorded with the laser tuned to the origin band of the S{sub 2}{l_arrow}S{sub 0} transition. The spectrum is consistent with the rapid radiationless transition from the S2 state into high vibrational levels of the S1 state, as proposed by Smith et al. Features in the double-resonance spectrum of Smith et al. that were previously assigned to photoionization of S(-) 3s(-){sup 1}A'{sub 2} vibrational levels populated by a radiationless transition from the S2 state are reinterpreted, with the conclusion that the S(-) state has yet to be observed.
