- 中文摘要: The gerade states of acetylene at 9-10 eV have been studied by monitoring the C/sub 2/ emission. Larger.DELTA..nu./sub 2/ excitations are seen than previously reported by Ashfold et al. The observed two-photon resonant levels show extensive predissociation. Experimental evidence from the two-color photofragment excitation measurement is given to support the conclusion that the excited-state ethynyl radical and atomic hydrogen are the corresponding predissociation products. Most C/sub 2/ emissions seen in this work are due to the subsequent photodissociation of the intermediate C/sub 2/H to C/sub 2/(d/sup 3/.PI./sub g/).
