✦ Synopsis

Term values of the (A^{1} \Pi, v=1) and 2 levels of ({ }^{12} \mathrm{C}^{18} \mathrm{O}) and (v=1) level of ({ }^{13} \mathrm{C}^{18} \mathrm{O}) from the experimental data of the (A^{\prime} I I-X^{\prime} \Sigma^{+})system (Haridass et al., J. Mol. Spectrosc. 167, 334-352, 1994) were calculated. Term values of the Rydberg states (B^{1} \Sigma^{+}, v=0) and (1, C^{1} \Sigma^{+}, v=0), and (E^{\prime} \Pi, v=0) of these two isotopomers were calculated by combining the data of the (A^{1} \Pi-X^{1} \Sigma^{+}) system and those of the (B^{1} \Sigma^{+}-A^{\prime} \Pi, C^{l} \Sigma^{+}-A^{1} I I), and (E^{1} \Pi-A^{\prime} \Pi) systems taken from the literature. The interaction between the (C) and (E) states was taken into account in determining their molecular parameters. Finally, the molecular constants of the (B, C), and (E) states of ({ }^{12} \mathrm{C}^{18} \mathrm{O}) and ({ }^{13} \mathrm{C}^{18} \mathrm{O}) were determined from the calculated term values.
