Abstract

Resonance enhanced multiphoton ionization spectra between 355 and 375 nm of CHCl/sub 2/ and CDCl/sub 2/ radicals are reported. The origin of the observed spectra was at 370.1 nm for CHCl/sub 2/ and 370.4 nm for CDCl/sub 2/. The REMPI mechanism is determined to be a 2 + 1 photon absorption, with the resonant intermediate state tentatively assigned as a 3d Rydberg state. Vibrational structure originated from activity in the C-Cl symmetric stretching and the out-of-plane bending modes. The C-Cl symmetric stretch frequencies are 845 cm/sup -1/ in CHCl/sub 2/ and 814 cm/sup -1/ in CDCl/sub 2/.
