On the Presence of Free Chlorine in Sodium Chloride Crystals Containing Color Centers and Color Center Precursors

Abstract

Measurements have been carried out of the free chlorine content of NaCl crystals subjected to electrolysis before and after exposure to x-rays, as well as the free chlorine content of normal NaCl crystals after irradiation. It has been found that crystals which have not been irradiated contain no free chlorine, whereas those exposed to x-rays contain between 0.1 and 0.6 free chlorine atom per vacancy pair.
