Sažetak
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.
