摘　　要：The photodissociation dynamics of jet-cooled HCO radical was investigated in the region of 490 nm to 715 nm using the H-atom high-n Rydberg time-of-flight(HRTOF)technique.The CO product rovibrational state populations are well resolved in the H+CO product translational energy distributions,and an accurate H-C bond dissociation energy D0(H-CO)=5086±5 cm^(-1)is obtained.本文利用高里德堡态氢原子飞行时间探测技术,在490到715纳米波长范围内研究了射流冷却HCO自由基的光解动力学.通过分析H+CO产物的平动能量分布,可以清晰分辨出CO产物的振动转动态分布,并精确测定了H-C键解离能,D0(H-CO)=5086±5 cm^(-1).
