英文摘要The photodissociation dynamics of carbonyl sulfide (OCS) in helium droplets was studied using a velocity-map- imaging technique. The CO fragments were detected by (2 + 1)- resonance-enhanced multiphoton ionization. It was found that in the helium droplet environment, rotational cooling is much more efficient than vibrational cooling. The velocity map images for both CO (v=0) and CO (v=1) exhibit nearly isotropic angular distributions. The kinetic energy distributions show that most of the translational energies are relaxed in the finite-sized superfluid helium system. However, the average translational energies of the CO (v=1) images are higher than those of the CO (v=0) images. The relevant mechanism is briefly discussed.
