The Production and Dispersed Laser Induced Fluorescence Spectrum of Dibromocarbene in Gas Phase

Abstract: Dispersed laser induced fluorescence spectra of gas-phase CBr2 and Br2 produced by the reaction of F atom with CH2Br2 in the microwave discharge flow tube apparatus have been measured. The dispersed fluorescence spectrum excited at 571.9 nm was assigned to A(0,13,0)→X(0,v2",0)( v2"=16)transitions of CBr2,the fundamental vibrational frequencies of bending mode of gas - phase CBr2 in electronic ground state was firstly derived from the spectrum to be v2"=215 cm-1 . The dispersed fluorescence spectrum excited at 575. 3 nm was assigned to B3Π+u →X1Σ+g transitions of Br2 . The generation of CBr2 and Br2 species is believed to be the second or third step reaction of F atom with CH2Br2 .
