Intensity Calculation of Some Optical Absorption Lines in Hydrated Manganous Salts

Abstract

The ligand field theory is applied to the hydrated manganous salts. The splitting of the degenerate levels of 4A1g and 4Eg is first investigated, and then the intensities of the transitions from the ground sextet 6Alg to these levels are calculated. The properties of the odd vibrations responsible for these transitions are also discussed. It is found that the calculated oscillator strengths are in good agreement with experiment if an appropriate model is used for the vibrations.
