Electronic absorption spectra of solutions of molecular chlorine in molten alkali metal chlorides

Abstract

Electronic reflection absorption spectroscopy has been used for measuring the electronic spectra of chlorine solutions in molten alkali metal chlorides 2CsCl-NaCl, KCl-NaCl, and CsCl in the range 240–400 nm. Absorption bands of chloride melts are interpreted as electronic transitions in the molecular group Cl2 and in the triatomic linear group Cl 3 − of symmetry D ∞h and C ∞V .
