摘要：

The extent of K-mixing in the dissociation of ketene on its So potential energy surface has been investigated. Using a two-step photodissociation scheme for ketene and laser-induced fluorescence (LIF) to detect the CH2 radical, photofragment excitation (PHOFEX) spectra of high energy selectivity were recorded. The ratio of the step heights shows that K is strongly mixed for K > 0 and that for K = 0 the extent of mixing increases with J. (C) 1998 American Institute of Physics. [S0021-9606(98)01621-3]
