我们描述了266 nm和292 nm激光照射火焰和室温流动的乙炔和乙烯在天鹅带跃迁的上层（d3Πg）和下层（a3Πu）产生的c2光化学产物。讨论的主题包括天鹅带光谱、天鹅带发射的寿命和猝灭、几种环境下天鹅带发射的强度依赖性、二氧化碳在低压碳氢化合物火焰中的分布，以及天鹅带发射对碳氢化合物火焰中原子氢的三光子激发荧光检测的影响。
We describe photochemical production of C2in the upper (d3Πg) and the lower (a3Πu) levels of the Swan-band transitions by 266 and 292-nm laser irradiation of flames and room-temperature flows of acetylene and ethylene. Topics treated include the spectroscopy of the Swan bands, lifetimes and quenching of the Swan-band emission, intensity dependences of the Swan-band emission in several environments, profiles of C2in low-pressure hydrocarbon flames, and the affect of Swan-band emission on three-photon-excited fluorescence detection of atomic hydrogen in hydrocarbon flames.
