Abstract

Photobromination of SiH4 under uv-irradiation at various wavelengths has been studied. Rate constants for the elementary reactions Br(2P3/2)+SiH4→HBr+SiH3 (k=3.2×10−11 exp(−21.8±2.5)/RT, cm3/s) and Br* (2P1/2)+SiH4→HBr+SiH3 (k*=(3±1)×10−13 cm3/s) have been determined in the temperature range from 300 to 415 K.
