We present a theoretical analysis of x-ray-absorption near-edge structure at one Sr K edge in La2-xSrxCuO4 and SrF2 compounds based on the experimental results of Z. Tan et al. [Phys. Rev. Lett. 64, 2715 (1990)]. Contrary to the suggestion put forward in this investigation which is based on the observation of a certain absorption structure, we obtain the best agreement with experimental data when the environment of the dopant Sr atom is kept fixed in its crystallographic arrangement.
