In this communication we suggest a formulation of the optical conductivity as a convolution of an energy-resolved joint density of states and an energy-frequency labelled transition rate. Our final aim is to develop a scheme based on the augmented space recursion for random systems. In order to gain confidence in our formulation, we apply the formulation to three alkaline-earth titanates, CaTiO3, SrTiO3 and BaTiO3, and compare our results with available data on optical properties of these systems.
