Abstract

Zero kinetic energy photoelectron spectroscopy of the weakly bound complex Cl(-).N(2)O is presented. Adiabatic detachment energies between the anionic complex and the neutral complex states X(1/2), I(3/2), and II(1/2) as well as frequencies of van der Waals modes are supplied. Supported by theoretical simulations, these results correlate with a T-shaped structure of the anionic and an L-shaped structure of the neutral molecular complex. The weakly bound neutral complex Cl.N(2)O has been discussed as a prereactive state of the chemical reaction Cl + N(2)O --> ClO + N(2) [A. Lesar, M. Hodoscek, M. Senegacnik, J. Chem. Phys. 1996, 105, 917].

摘要

本文介绍了弱束缚复合物Cl(-).N₂O的零动能光电子能谱。给出了阴离子复合物与中性复合物态X(1/2)、I(3/2)和II(1/2)之间的绝热脱离能以及范德华模式的频率。在理论模拟的支持下，这些结果与阴离子的T形结构和中性分子复合物的L形结构相关。弱束缚中性复合物Cl.N₂O已被讨论为化学反应Cl + N₂O --> ClO + N₂ [A. Lesar, M. Hodoscek, M. Senegacnik, J. Chem. Phys. 1996, 105, 917]的预反应态。
