Description
The continuous-time photoelectron spectroscopy was proposed to study the monochromatic soft x-ray photodissociation of CF3Cl molecules adsorbed on Si(111)-7x7. Evolution of adsorbed CF3Cl was monitored at two photon energies of 240 and 730 eV to deduce the photolysis cross section as a function of energy. Dissociation of adsorbed CF3Cl by 240/730 eV photons is attributed to the C-Cl/C-F bond scission following the excitation of Cl(2p)/F(1s) core electron. Observation of time-dependent photodissociation also demonstrates the capability for 'real-time' monitoring of the variations of electronic structure and chemical bonding of adsorbate in bond-selective photochemistry
