Abstract:
Anionic fragments, F- and Cl- including two isotope species 35Cl- and 37Cl-, are ob-served in the photoexcitations of CFCl3. The ion-pair anion e±ciency spectra of 35Cl- and 37Cl- are recorded in the photon energy range of 7.75~22.00 eV. The threshold of ion-pair dissociation CFCl3→CFCl2++Cl- is experimentally determined to be 7.94±0.04 eV. With the references of the high-resolution photoabsorption spectra reported in the literatures, we make tentative assignments of the electron valence-to-Rydberg transitions. Furthermore, the multibody ion-pair fragmentation processes to Cl- are discussed by comparison between the calculated thermochemical thresholds and the experimental efficiency spectrum.

摘要:
在CFCl3分子的同步辐射光激发正负离子解离过程中,利用负离子飞行时间质谱技术观测到了F-和Cl-(包括35Cl-37Cl-),测量得到了35Cl-37Cl-在7.75~22.00 eV的负离子产额效率谱. 实验得到CFCl3→CFCl
