Hyperfine interaction in hydrogen and deuterium atoms stabilized in frozen-gas matrices

The isotopic effect in relative matrix shifts of hyperfine structure constants of H and D atoms is considered, and its quantitative estimation is determined for hydrogen and deuterium atoms stabilized in krypton and argon matrices. The quantitative estimation is in good agreement with the experimental results. The effect of zero oscillations taken into account improves the agreement between the theoretical and experimental values of matrix shifts
