Derivations of 18O Abundances in Comets Using the Ultraviolet Bands of 18OH
Abstract
A fluorescent equilibrium model for the 1-0 band of the A-X system of 18OH has been constructed. Line positions and intensities have been calculated for possible future spectroscopic observations of these bands from space in order to derive 18O/16O ratios in comets. It is demonstrated that the strong lines of the 1-0 band can be observable for a moderately bright comet using a high resolution spectrometer with a reasonable exposure time.
