The red band of CuO has been observed at high resolution using Intracavity Laser Spectroscopy (ILS). The red band was rotationally analyzed in 1974 by Appelblad and Lagerqvist and a portion of the band structure was assigned as the spectrum of the [16.5] textitA 2Sigma+ - textitX 2Pii transition. Subsequent analyses of CuO showed that the character of the textitA state was 2Sigma− in character, and thus the Lambda-doubling parameter, textitp, was inverted, and the textite/textitf parity assignments were reversed. In this study, the spectrum of CuO was recorded in the in the regions 16,150 wn – 16,270 wn and 16,405 wn - 16,545 wn. The CuO molecules were produced in the plasma discharge of a copper hollow cathode within the cavity of a tunable dye laser, using 0.6 torr of argon as the sputter gas and a trace amount of chem{O_2} as the source of oxygen. The plasma spectra were recorded intermittently with spectra from an external chem{I_2} cell, and line positions from the widely used Iodine Atlas were used for calibration. In uncongested regions of the spectrum, both 63CuO and 65CuO were observed with appreciable intensity. The resulting spectra were rotationally analyzed for both isotopologues, fitting the data as a 2Sigma− - 2Pii transition using PGOPHER. Line positions from the millimeter wave and FTIR studies of 63CuO performed in the late 1990s were included in the fit to overcome potential complications due to the ambiguous parity assignments prevalent in the CuO literature. Previously unreported molecular constants were obtained from the fit for 65CuO, and the constants of 63CuO are determined to at least an order of magnitude greater than the results of Appelblad and Lagerqvist. Results of this analysis will be presented.
