Within the pseudopotential approach, studies were made of the chemical shift effect on the following characteristics of the electronic states of impurity centres; the energy level spectra, polarizability, diamagnetic susceptibility and the probability of non-radiative phonon transitions. It is shown that the most sensitive parameter is the phonon widths of the donor levels which may differ from hydrogen-like values by several orders of magnitude for a small (<10%) chemical shift.
