In all cases activation is sufficient to convert ethylene efficiently into its triplet state. Two different behaviors of laser excited ethylene are discussed. They depend on which line the laser is tuned to. Considering that two IR active modes extend their rotational manifolds over the range covered by CO2 laser radiations (谓7 and 谓10), it is believed that the different laser lines energize selectively either one of them.MODE SELECTIVE LASER CHEMISTRY OF ETHYLENE期刊论文EnglishDEHEMPTINNE, X; DEKEUSTER, D WOS:A1980KJ69300020
