Abstract
Systematic experimental measurements have been carried out on the crystal field and charge transfer spectra for divalent cobalt ions in a series of alkali halide crystals. The influence of divalent lead ions on these spectra has also been investigated. Additionally, the spectrum of Co++ in acetone with LiCl has been studied and the charge transfer band is found to be absent. The analysis of these measurements and earlier data indicate that the interstitial model for the cobalt complex in KCl proposed in the literature is unsatisfactory. An alternate model involving regions in which double salts (such as M2CoCl4) are present is shown to successfully explain the available data.Keywords
