Absorption spectrum of rubidium and cesium dimers by compact computer operated spectrometer

In this paper we are presenting the visible absorption spectrum of both rubidium and cesium vapor in the 570-870 K temperature range. We used a classical absorption spectroscopy experimental scheme with several new features. The first concerns the use of modern, compact, computer operated spectrometer (Ocean Optics HR4000CG-UV-NIR), which allowed us to record spectra instantaneously resulting in higher signal-to-noise ratio. The second improvement is connected with the use of the all-sapphire cells (ASC) enabling work with a high density of alkali atoms within precisely defined vapor column. In the superheated regime (above 700 K) thermal destruction of dimer molecules clearly distinguishes triplet from singlet transitions.
