Absolute rate constants for the reaction of SiH with hydrogen, deuterium and silane

Abstract

Silylidyne, SiH, has been generated by excimer laser flash photolysis and its concentration monitored in real time by laser-induced fluorescence. Removal rates for SiH by hydrogen, deuterium and silane have been determined at 5 Torr total pressure in helium at ambient temperature. Silylidyne reacts gas-kinetically with silane, but considerably more slowly with hydrogen and deuterium. © 1989.
