英文摘要	from the photofragment translational spectra of c-h symmetric stretch excited ch3i [v(1) = 1, v(2) = 0] photodissociatioin at 277.5 nm, the vibrational distribution of photofragments ch3 (v(1) = 0, v(2) = 0), (0,1), (1,0), (1,1) in the i* channel are measured to be 0.02, 0.02, 0.47, 0.25, and those of ch3 (1,0), (1,1) in the i channel are 0.04, 0.05, respectively. it shows that most of the dissociated ch3i [1,0] retain the c-h symmetric stretch vibration v(1) = 1 in the photofragments ch3, and the vibrational distribution in umbrella bending mode is not seriously affected by the original ch symmetric stretch excitation. the photodissociation of ch3i [1,0] mainly follows the vibrationally adiabatic process. the original vibrational excitation [v(1) = 1] of ch3i is quite like a spectator, and the intramolecular vibrational-energy redistribution (ivr) does not play obvious part during photodissociation.
