✦ Synopsis

The characteristic '2: +'X$ absorption band of Art near 300 nm is found to remain essentially intact in Art as well as the larger argon clusters. This absorption is slightly blue-shifted and of about half the intensity of the Art absorption. We account for these observations with a model invoking an Art d Ar double minimum ground state for Ar$ and suggest that the visible spectrum of this species arises from an intracluster electron transfer excitation.
