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 ¹²C¹⁶O, ¹³C¹⁶O, ¹²C¹⁸O, and ¹²C¹⁷¹²C¹⁶O. 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 ¹³C¹⁸O.
