用H(D)原子里德堡标记飞行时间技术研究了喷射冷却的HOD在124 nm附近通过(C)跃迁态的光解离.记录了D+OH和H+OD解离通道的旋转态分辨作用谱和产物平动能分布谱。测定了分子(C)与分子(X)、分子(X)与分子(C)、分子(X)、分子(C)、分子(X)、分子(X)、分子(X)在分子轨道上的产物通道OH/OD分支比。文中还给出了与波浪线上的(B)、波浪线上的(X)和波浪线上的(A)波浪线-(X)之间的比较。此外，还准确地测定了高取代基团中OD键的离解能为41751.3+/-5 cm(-1)。
Photodissociation of jet-cooled HOD via the (C) over tilde state around 124 nm has been studied using the H(D)-atom Rydberg tagging time-of-flight technique. Rotational state resolved action spectrum and the product translational energy distribution spectra have been recorded for both D+OH and H+OD dissociation channels. Product channel OH/OD branching ratios for the individual (C) over tilde-(X) over tilde rotational transition have been determined. A comparison is also given with the (B) over tilde-(X) over tilde and (A) over tilde-(X) over tilde transitions. In addition, the dissociation energy of the OD bond in HOD has been determined accurately to be 41751.3 +/- 5 cm(-1).
