Pm. Chu et al., PHOTODECOMPOSITION OF MO(CO)(6) SI(111) 7X7 - CO STATE-RESOLVED EVIDENCE FOR EXCITED-STATE RELAXATION AND QUENCHING/, The Journal of chemical physics, 101(4), 1994, pp. 2929-2939
State-resolved detection techniques have been used to characterize the
ultraviolet photodecomposition dynamics of Mo(CO)(6) on Si(111) 7x7 a
t 100 K. Details of the excitation/fragmentation mechanism including a
dsorbate energy transfer were examined by measuring the cross sections
and the internal and translational energies of the photoejected CO fr
om submonolayer through multilayer coverage regimes. The CO energy dis
tributions are found to be independent of Mo(CO)(6) coverage, and can
be characterized by two components with markedly different mean energi
es. In contrast to the coverage independence of the measured energy di
sposal, the cross section was found to decrease by a factor of 3 from
multilayer coverages to submonolayer coverages.
