Abstract: A 10-meter Czerny-Turner infrared spectrometer has been modified and adapted into an instrument with a 50 cm focal plane suitable for photographic recording of spectra between about 1800 and 8000 Angstroms. The $20 cm \times 40 cm$ Bausch and Lomb plane grating used in the Czerny-Turner system has been precisely calibrated employing several standard wavelengths. The emission spectrum of $CO^{+}$ has provided a good test for the resolution of the remodeled spectrograph in the ultraviolet. A hollow cathode discharge lamp has been employed to generate the 0-0, 0-1, and 0-2 bands of the $B^{2}\Sigma^{+}-X^{2}\Sigma^{+}$ system of $^{12}C^{16}O^{+}$ and $^{13}C^{16}O^{+}$ in emission. A nonlinear least-squares fitting rountine has been used to analyze the bands. In the case of $^{12}C^{16}O^{+}$, current data have been analyzed taking full advantage of available microwave data for the ground state, thereby permitting comparisons with previous results. Results of the study on $^{13}C^{16}O^{+}$ provide the first determination of molecular constants for this isotopic species in the $B^{2}\Sigma^{+}$ and the $X^{2}\Sigma^{+}$ electronic states.
