The reaction times of several well-defined channels of the C-I bond rupture of methyl iodide from the A band, which involves nonadiabatic dynamics yielding ground state I({sup 2}P{sub 3/2}) and spin-orbit excited I*({sup 2}P{sub 1/2}) and ground and vibrationally excited CH{sub 3} fragments, have been measured by a combination of a femtosecond laser pump-probe scheme and velocity map imaging techniques using resonant detection of ground state CH{sub 3} fragments. The reaction times found for the different channels studied are directly related with the nonadiabatic nature of this multidimensional photodissociation reaction.
