In this work we present calculations of the contribution of the Breit interaction between moving electrons and nuclei on the spin-rotation constant for model systems HX (X = H, F, Cl, Br, I) obtained with a full four-component theoretical expression, which was recentlyproposed by the authors of this work.The contributions obtained are by far much smaller than relativistic effects given within the 4-component theory of the Born-Oppenheimer main contribution.
