High-Resolution Spectroscopy of the X-A Transition of the Carbon Monoxide Dication CO${}^{2+}$

X. Huet, A. Aerts, N. Vaeck +2

We report rovibronic spectra of the A ${}^3\hat{I}{\pounds }^{+}$($v^{\prime }=0-2$) - X ${}^3{\hat{I}}_{\hat{I}}\text{c◯}(v=0)$ rovibronic transitions ($|\hat{I}\text{c◯}|=0,1$ and 2) of the CO${}^{2+}$ doubly-charged molecular ion. Spectra were r…
