Abstract

The rate coefficient for NH~2~ + CH~4~ → NH~3~ + CH~3~ (R1) has been measured in a shock tube in the temperature range 1591–2084 K using FM spectroscopy to monitor NH~2~ radicals. The measurements are combined with a calculation of the potential energy surface and canonical transition state theory with WKB tunneling to obtain an expression for k~1~ = 1.47 × 10^3^ T ^3.01^ e^−5001/T(K)^ cm^3^ mol^−1^ s^−1^ that describes available data in the temperature range 300 –2100 K. © 2003 Wiley Periodicals, Inc.
