We have studied the kinetics of N-2(X,nu) with silane. These experiments were done in a discharge-flow reactor and used N-2(X,nu) diagnostics employing metastable energy transfer reactions. To investigate vibrational levels greater than five, and up to at least thirteen, we analyze N-2(B(3)Pig,nu'less than or equal to12) fluorescence excited in the interaction between metastable N-2(A(3)Sigma(u)(+)) and N-2(X(1)Sigma(g)(+),nu). N-2(+) (B(2)Sigma(g)(+),nu'=0-8) fluorescence, excited when metastable helium atoms collide with N-2(X,nu), diagnoses vibrational levels between one and six. The rate coefficients for quenching vibrationally excited nitrogen by silane range from 1 x 10(-13) to 6 x 10(-13) cm(3) molecule(-1) s(-1), being higher for the higher vibrational levels. Observations at 4500 nm show that at least one channel for the N-2(X,nu) quenching process involves excitation of SiH4(nu(3)). Comparison of the relative excitation rate of SiH4(nu(3)) with that for N2O(nu(3)) excitation when N2O is added to the reactor, however, indicates that at most 15% of the N-2(X,nu) quenching events result in nu(3) excitation. Presumably the rest of the energy is absorbed by other vibrational modes.
