A particular type of surface chemical reaction resulted in direct charge ejection. Several different experimental observations strongly support the hypothesis that nearly all of the molecular kinetic energy of a highly excited vibrating molecule was transferred to the kinetic energy of a single electron in a conducting lattice, leaving the molecule in nearly its ground state. This kinetic energy transfer represents the counterpart to the potential energy transfer in a battery, where electrochemical potential energy of reactants is transferred to the electrical potential energy of a separated charge. Here chemical reaction energy is transferred directly to the kinetic energy of a charge instead of to the potential energy of a charge. These observations indicate a breakdown of the Born Oppenheimer approximation.

我们开发了一种理论方法来解决量子力学反应散射问题的存在下的外部领域的基础上的超球坐标描述的反应配合物结合总角动量表示的碰撞在外部领域。该方法使我们能够得到电场中LiF + H -> Li + HF化学反应的收敛结果。我们的计算表明，通过诱导不同的总角动量的状态之间的耦合，电场与幅度<150 kV/cm引起的共振散射和显着修改的总反应几率，产品状态分布和分支比的反应与非弹性散射。
