Trimethylchlorosilane, (CH3)3SiCl: OH reaction kinetics and infrared spectrum

Abstract : Rate coefficients for the OH + (CH3)3SiCl (trimethylchlorosilane) gas-phase reaction were measured over the temperature range 295–375 K using a pulsed laser photolysis laser-induced fluorescence technique. The room temperature rate coefficient was determined to be k1(295 K) = (2.51 ± 0.13) × 10−13 cm3 molecule–1 s–1. The Arrhenius expression k1(T) = (7.06 ± 2.15) × 10−12 exp[–(992 ± 101)/T] cm3 molecule–1 s–1, where the quoted uncertainties are 2σ fit precision, describes the measured temperature dependence very well. As part of this work, the infrared spectra of CH3)3SiCl was measured.
