ArOH and ArOD van der Waals complexes are of interest because they are prototypical molecules for studying the interactions between an open-shell radical and an inert gas atom. Recently, several groups have reported spectroscopic investigations of these $complexes.1,2$ In particular, Fawzy and Heaven found that there are two distinct band types in ArOH. Much work has been done on the spectra, but questions remain. In collaboration with Fawzy and Heaven, we have observed LIF spectra of ArOH with higher resolution with the aim of getting more detailed information about the complex. The experiments on ArOD are also in progress. Implications of the high resolution spectra of these open-shell van der Waals complexes will be discussed
