The reaction between CH3 radicals and H-2 was investigated behind inci
dent shock waves at temperatures between 1308 and 1825 K by following
the consumption of CH3 using a time resolved UV absorption method at 2
13.9 nm. The rate coefficient expression 1.10X10(13) exp(-7370 K/T) cm
(3)mol(-1)s(-1) for the reaction of CH3 with H-2 was derived.
