采用多参考组态相互作用方法和aug-cc-pV5z基组并虑及Davidson修正计算了反应体系F+H2→HF+H的约15,000个对称性唯一的构型点的势能值,并利用三次样条插值发展了该体系的三维全域势能面.在反应入口通道,还考虑了旋轨耦合效应.
採用多參攷組態相互作用方法和aug-cc-pV5z基組併慮及Davidson脩正計算瞭反應體繫F+H2→HF+H的約15,000箇對稱性唯一的構型點的勢能值,併利用三次樣條插值髮展瞭該體繫的三維全域勢能麵.在反應入口通道,還攷慮瞭鏇軌耦閤效應.

A global three dimensional potential energy surface for the F+H2→HF+H reaction has been developed by spline interpolation of about 15,000 symmetry-unique ab initio points, obtained from the multi-reference configuration interaction level with Davidson correction using the aug-cc-pV5Z basis set. In the entrance channel the spin-orbit coupling energy is also included.
