Abstract:Ultraviolet spectrographs on space-borne astronomical facilities are used to study CO photochemistry primarily through observations of the $A-X$ Fourth Positive Band System. Absorption from $^{12}$C$^{16}$O, $^{13}$C$^{16}$O, $^{12}$C$^{18}$O, and $^{12}$C$^{17}$O in diffuse interstellar clouds has been detected to date. While the necessary spectroscopic data are available to identify the isotopologues, measurements of oscillator strengths only exist for the most abundant variant, $^{12}$C$^{16}$O. In our ongoing experiments on the DESIRS beam-line at the SOLEIL Synchrotron, we are acquiring the necessary data on oscillator strengths and term values for other isotopologues. Here we present our latest results involving $A-X$ bands in $^{13}$C$^{18}$O.
