LIF STUDIES OF SIMPLE HALOCARBENES

Author Institution: Department of Chemistry, Marquette UniversityWe will report on new laser induced fluorescence (LIF) measurements of the $A^{1}A^{\prime\prime}-X^{1}A^{\prime}$ system in the monohalocarbenes HCCl and HCF, and the $A^{1} B_{1}-X^{1} A_{1}$ system in the dihalocarbene $CCl_{2}$. The carbenes were generated under jet-cooled conditions using a pulsed discharge source. We have applied a variety of techniques to examine the excited state properties, and results from fluorescence excitation spectroscopy, single vibronic level lifetime measurements, and quantum beat spectroscopy will be reported
