Abstract
The Yellow-Green band system of $TiCl^{+}$ has been studied using a dual-beam laser absorption technique in a hollow cathode $discharge^{m}$, 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 $TiCI_{4}$ 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 $emission^{o}$ and $absorption^{p}$ spectra of $TiCl^{+}$. Molecular parameters and internuclear distances for the [17.9]$^{3} \Delta$ and $X^{3}\Phi$ states of the $^{48}Ti^{35}Cl^{+}$ and $^{48}Ti^{37}Cl^{+}$ isotopomers will be presented.
