The methodology presented in the previous talk has been applied to the electronic spectroscopy of the $CF3O$ radical, which has a $\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}E$ ground state and a $\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}A$ first excited state under $C3\nu$ symmetry. Previous work in our laboratory has produced the laser-induced fluorescence excitation spectrum of this radical, along with the dispersed emission spectra from the first three levels of the excited state. These spectra suggest that the $CF3O$ radical has in its ground state strong first-order Jahn-Teller coupling, significant spin-orbit coupling, and weak second-order Jahn-Teller coupling. The combination of these effects yields quite complicated spectra. The spectra of other Jahn-Teller active radicals will also be discussed.
