Comparison of observed isotope ratios (or abundances) with theoretical expectations can then be used as a check on the occurrence of such phenomena as convection, meridional mixing, and mass loss.

https://doi.org/10.1007/978-3-662-66225-0 together with rocket observations of the CO ultraviolet bands (Smith and Stecher, 1969) has provided our total knowledge of the relative abundance of .C in the very local (d < 200 pc) interstellar gas contained in the diffuse clouds typified by the ζOph cloud.

https://doi.org/10.1007/978-3-662-66225-0 are similar; thus the ratio of their intensities directly provides an abundance ratio. Whether chemical fractionation of the oxygen isotopes occurs, as it might be the case for the carbon isotopes (Watson, this book), is unknown; thus we do not know to which extent the .O/.O ratio is equal to the C.O/C.O ratio.
