采用 CASSCF 和CASPT2 方法研究了Criegee 中间体CH2OO 的光化学反应机理。结果发现：CH2OO 受光激发到S2 态后，可发生O-O 键解离过程，并在O-O键断裂前后抵达S2 与S1 态间的交叉点；此时分子既可保持原Cs 对称性发生进一步解离，又可自发地沿C-O 键旋转的方向弛豫到S1 态，并趋向于形成垂直结构。
Activation of C-H bond in propane by Pd(Ⅱ)-catalysts bearing ligands with charge-shift bonding chara
Using density functional theory(DFT),we have investigated the conversion of propane to propyl trifluoroacetate catalyzed by five kinds of(bis-2BB)PdBr2 complexes(bis-2BB is the derivatives of bis-2-bo

氧分子对钙钛矿的影响在实验中已被广泛研究，但是理论上的机理研究仍比较欠缺。本文尝试通过第一性原理的计算揭示氧分子和钙钛矿作用的微观机理。研究结果表明氧分子是通过范德华力吸附在钙钛矿的表面，这种吸附会使钙钛矿表面产生少量诱导正电荷(相应地，氧分子上产生诱导负电荷)。
