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. 相似文献
