The Yellow-Green band system of $TiCl+$ has been studied using a dual-beam laser absorption technique in a hollow cathode $dischargem$, and conventional emission spectroscopy. The quartz discharge cell for emission spectroscopy consisted of a 5 cm long, 2 mm internal diameter capillary similar to that used for a velocity modulation emission $spectroscopy.n$ The discharge was modulated at 25-125 kHz by a power supply which produced a bipolar me wave. Samples of $TiCI4$ in Ar were flowed slowly through the cell from the center of the capillary and symmetrically pumped out via the electrodes. The Yellow-Green band system was observed previously in the $emissiono$ and $absorptionp$ spectra of $TiCl+$. Molecular parameters and internuclear distances for the [17.9]$\mathrm{<mrow\; data-mjx-texclass="ORD">3</mrow>}\Delta$ and $X3\Phi$ states of the $\mathrm{<mrow\; data-mjx-texclass="ORD">48</mrow>}Ti35Cl+$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">48</mrow>}Ti37Cl+$ isotopomers will be presented.
