N2 - Based on spectroscopy of the (3s3p)3P0-(3s3d)3D1 Mg i transitions for the stable isotopes Mg24(I=0),Mg25(I=5/2), and Mg26(I=0) we report measurements of the Mg25(3s3d)3DJ hyperfine coefficients A(3D1)=141±7,A(3D2)=-59±6, and A(3D3)=-97±3MHz. We find the hyperfine coefficients in agreement with state-of-the-art theoretical predictions presented here giving A(3D1)=143.3±1.4,A(3D2)=-48.3±0.5, and A(3D3)=-96±1MHz. We also report measurements of the isotope shifts for the investigated transitions Δ24-25=6±9 and Δ24-26=59.7±0.5MHz, significantly reducing the uncertainty compared to previous measurements.
