Last year at this meeting, we reported studies of the predissociated, quasilinear B^{1}A^' state of fluorocarbene (CHF and CDF) using a fluorescence dip detected optical-optical double resonance technique via the A^{1}A^'' state. Recently, we have extended these observations to chlorocarbene, measuring OODR spectra of both CH^{35}Cl and CD^{35}Cl. By recording OODR spectra of both isotopomers, we are able to pinpoint the origin of the B^{1}A^' state, while lies near 22 400 cm^{-1}. In contrast to CHF, the B^{1}A^' origin in chlorocarbene lies below the energetic threshold of the lowest dissociation channel, C(^{3}P) + HCl. However, at higher energies several channels open up, including C-H and C-Cl bond fission, and the OODR spectra show significant lifetime broadening. Trends in the measured linewidths with energy will be discussed.
