Abstract
We have measured the A-X visible system of the $H_{2}O^{+}$ and $D_{2}O^{+}$ using a ring dye laser and velocity-modulation spectroscopy. All previous experimental studies of this system have been in emission. Our $results^{1}$ in $H_{2}O^{+}$ have much better measurement of intensities than previous $work^{2}$. The best previous work in the visible on $D_{2}O^{+}$ was obtained by Lew and $Groleau^{3}$, using emission spectroscopy of a discharge with a grating monochromator. They reported fragmentary results in the $V_{2}=10\leftarrow0$ band. Our new results in $D_{2}O^{+}$ are more extensive than previous work in this band, and disagrees with previous work by many standard deviations.
