Notes

Abstract: The kinetics of the reaction H(1²S) + SiH4 have been measured from 290 to 660 K by the flash photolysis-resonance fluorescence technique. The results are summarized by k = (1.78 ± 0.11) x 10(-10) exp[-(16.0 ± 0.2) kJ mol-1/RT] cm3 s-1 with a confidence interval of about ± 10%. The transition state for direct H-atom abstraction was investigated theoretically, at up to the Gaussian 2 ab initio level. A transition state theory analysis of the abstraction channel gives excellent accord with the measurements, which suggests that H2 + SiH3 are the dominant products. An expression for the reverse reaction is given. An extrapolated k from 290 up to 2000 K, which includes a Wigner tunneling correction, is k = 2.44 x 10(16) (T/K)1.903 exp(-1102 K/T) cm3 s-1.
