Beschreibungen/Notizen

• Formyl radicals, excited to specific rovibrational levels of the strongly bent B 2 A′ state are photoionized to form vibrationally excited states of the linear cation by the absorption of a tunable pulse of ultraviolet light from a second laser. Strong and essentially continuous photoionization spectra, which appear at intervals lying 7000 and 12 000 cm −1 above the adiabatic threshold, establish that formyl radicals can be efficiently ionized with a large geometry change at both energies. Non-Franck–Condon intensities suggest multiquantum pathways for vibrational autoionization.
