摘要: From laser‐induced fluorescence measurements, the OD:OH product branching ratio is determined to be greater than 25:1 for reaction H+HOD(001) and less 1:8 H+HOD(100). Fast H atoms are generated by photolysis of HI at 266 nm HOD excited a specific vibronic state using an optical parametric oscillator. Here HOD(001) HOD(100) correspond O–H O–D local‐mode stretch fundamentals, respectively. Within our signal‐to‐noise level, occurs exclusively with extended hydrogen atom in each case.
