Efficiency of selective IR multiphoton dissociation of molecules in a pulsed gas-dynamic flow interacting with a solid surface

Isotopically selective IR multiphoton dissociation of molecules (SF₆, CF₃I) in a pulsed gas-dynamic flow interacting with a solid surface was studied for the first time. A noticeable (severalfold) increase in the yield of products (compared to excitation of molecules in an unperturbed flow) without a substantial decrease in the selectivity of the process was observed. Possible reasons for the effect are discussed.
