A new method of theoretical low‐temperature calculation of the memory functions (MF) governing the exciton propagation in a model of a three‐dimensional perfect crystal with one molecule per elementary cell is presented. This method is suitable for all MF irrespective of distance between sites involved. The influence of initial condition on the exciton propagation is also tested.
