Abstract
The past decade has seen much spectroscopic work on clusters of transition-metal atoms. Cluster production methods have generally hindered sensitive detection of rotational band structure, leaving some duster geometries and electronic-state symmetries indeterminate. Here we show how a rf sputtering chamber produces copious dimers with a near-room-temperature rotational state distribution, allowing straightforward probing of rovibronic structure by laser-induced fluorescence (LIF). Dicopper, Q12, serves as the example.
