导出所有 H-3(+) + H-2 同位素变体反应的状态间热速率系数，并将其与新的实验数据进行比较。寒冷环境的天体化学建模也寻求理论数据（D-3(+) + H-2 速率系数表明当达到更高温度时反应机制发生变化。实验和理论之间良好的总体一致性鼓励使用天体物理建模的理论预测。(C) 2009 美国物理研究所。[DOI: 10.1063/1.3089422]
State-to-state thermal rate coefficients for reactions of all H-3(+) + H-2 isotopic variants are derived and compared to new experimental data. The theoretical data are also sought for astrochemical modeling of cold environments ( D-3(+) + H-2 rate coefficient indicates a change in reaction mechanism when going to higher temperatures. The good overall agreement between experiment and theory encourages the use of the theoretical predictions for astrophysical modeling. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3089422]
