非辐射DKR过程：理论的再探讨。II。电子-振动模耦合
Nonradiative DKR processes: revisiting the theory. II. Electron-vibrational mode coupling
摘要：
我们总结了几个建议，通过调解适当的破环振动模式的混合F中心状态。电子模耦合能量奇数阶的模式坐标的特点是由一个奇宇称振动模式介导的近简并的反宇称电子态的伪Jahn-Teller混合。耦合能量偶数阶振动坐标导致伪伦纳混合的偶宇称近简并态或动态伦纳混合的简并态的任何对称性。这两个伦纳混合能量加起来，以扩大交叉分裂的绝热能量，从而提高非辐射退激率。
英文摘要：
We summarize a few proposals for mixing F center states through the mediation of an appropriate symmetry-breaking vibrational mode. Electron-mode coupling energies odd-order in the mode coordinates are characteristic of the pseudo-Jahn-Teller mixing of nearly-degenerate opposite-parity electronic states mediated by an odd-parity vibrational mode. Coupling energies even order in the vibrational coordinates lead to a pseudo-Renner mixing of even parity nearly-degenerate states or to dynamic-Renner mixing of degenerate states of whatever symmetry. Both Renner mixing energies add up to widen the crossover splitting of the adiabatic energies thereby enhancing the nonradiative deexcitation rate.
