Abstract

$C F C I 2$ and $C F 2 C I$ Radicals were observed between 365-410 nm using resonance enhanced multiphoton ionization specetroscopy. Both spectra were generated by two-photon resonances with planar 3p Rydberg states. A third laser photon ionized the radicals. The $C F 2 C I$ spectrum displayed a vibrational progression assigned to the out-of-plane bending $ν 4' (b 1)(O P L A)$ mode $(ω 4' =745 c m −2$ ), with the origin at 406.2 rim ( $ν 0− o =49,230 c m −1$ ), Assignments for the $C F C l 2$ radical included the $ν 4' (h 1) O P L A (ω 4' =590(20) c m −1$ ) and the $ν 3' (a 1) C C l 2$ scissors $(ω 2' =270(30) c m −1$ ) modes, with the origin at $401.1 n m (ν 0−0 =49,850 c m −1)$
