摘要
The two-photon dissociation dynamics of (CO)-C-13-O-16 is studied using a tunable ArF excimer laser and the velocity map imaging technique. C(D-1) atoms formed are detected via (1 + 1) resonance-enhanced multi-photon ionization (REMPI). The measured C(D-1) yield spectrum is assigned to the a(3)Pi(nu = 2) <-- X-1<Sigma>(+) (nu = 0) transition. Images containing velocity and angular distribution information are measured for the Q(1), R(0) and R(1) lines. The dissociation energy is confirmed to be 11.09 +/- 0.02 eV. Dissociation takes place after one-photon excitation of the a(3)Pi (1)(nu = 2) state via a Delta Omega = 0 (parallel) transition. A suggested dissociation process is predissociation of a(3)Pi (1) Rydberg state on a 16 +/- 5 ps time scale. (C) 2000 Elsevier Science B.V. All rights reserved.
