通过电子再激发研究双生子复合动力学:阴离子CTTS光系统的动力学分析
Geminate recombination dynamics studied via electron reexcitation: Kinetic analysis for anion CTTS photosystems
摘要:
最近,它成为切实可行的研究双生复合动力学的溶剂化电子在极性液体中,通过使用短脉冲的光重新激发这些电子回到液体的导带和观察的变化,逃脱双生复合的电子的分数。在这封信中,这种技术的潜力,提供额外的深入了解电荷转移到溶剂(CTTS)的光剥离产生的电子在极性液体中的单价阴离子的重组动力学理论研究。由此产生的表达式解释了加州大学洛杉矶分校的B. J. Schwartz小组最近对Na-在四氢呋喃中的电子光剥离的结果。
英文摘要:
Recently, it became practicable to study geminate recombination dynamics of solvated electrons in polar liquids by using short pulses of light to reexcite these electrons back into the conduction band of the liquid and observe a change in the fraction of electrons that escape geminate recombination. In this Letter, the potential of this technique to provide additional insight into the recombination dynamics of electrons generated by charge-transfer-to-solvent (CTTS) photodetachment from monovalent anions in polar liquids is studied theoretically. The resulting expression accounts for the recent results from B.J. Schwartz's group at UCLA for electron photodetachment from Na- in tetrahydrofuran.
