Photodissociation of HCO Radical via ?2A" State:Accurate Determination of Bond Dissociation Energy D0(H-CO)
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)tech-nique.The CO product rovibrational state populations are well resolved in the H+CO product translational energy dis-tributions,and an accurate H-C bond dissociation energy D0(H-CO)=5086±5 cm-1 is obtained.
