A theoretical ab-initio study of optical properties of ScPd3 and YPd3 is presented. The agreement of this work with the experimental data for YPd3 in the high energy range is excellent. In the low energy range a sharp narrow peak in YPd3 is obtained which is not observed experimentally due to Drude's correction. In the case of ScPd3 this low energy is shifted somewhat towards higher energy and it is very intense, hence more probable to be observed.
