英文摘要one of the fundamental photoreactions for ketones is norrish type i reaction, which has been extensively studied both experimentally and theoretically. its a bond-cleavage mechanisms are usually explained in an adiabatic picture based on the involved excited-state potential energy surfaces, but scarcely investigated in terms of a non-adiabatic picture. in this work, the s-1 alpha bond-cleavage reactions of ch3oc(o)cl have been investigated by using the casscf and mrci-sd calculations, and the ab initio based time-dependent quantum wave-packet simulation. the numerical results indicate that the photoinduced dissociation dynamics of ch3oc(o)cl could exhibit strong nonadiabatic bond-fission characteristics for the s-1 alpha c-cl bond cleavage, while the dynamics of the s-1 alpha c-o bond cleavage is mainly of adiabatic characteristics. this nonadiabatic mechanism for norrish type i reaction of ch3oc(o)cl is uncovered for the first time. the quantum wavepacket dynamics, based on the reduced-dimensional coupled potential energy surfaces, to some extent illustrates the significance of the nonadiabatic effect in the transition-state region on the dynamics of norrish type i reaction.
