Abstract The electronic transitions from the ground state to the 3d states have been studied for23Na and7Li atoms by two-photon Doppler-free laser spectroscopy. The positions of the resonances are used to determine the unresolved hyperfine structure of the 3d states from which the magnetic-dipole hyperfine interaction constantsA are derived. The results for theA factors are:A(3d 2 D 3/2;23Na)=+527(25) kHz;A(3d 2 D 5/2;23Na)=+108.5(2.4) kHz;A(3d 2 D 3/2;7Li)=+843(41) kHz;A(3d 2 D 5/2;7Li)=+343.6(1.0) kHz. For the fine structure intervals fs of the 3d doublets we obtain: fs(3d Na)=-1 494 444(44) kHz and fs(3d Li)=+1 083 936(60) kHz. The linewidths of the resonances are evaluated with respect to the natural lifetimes of the 3d states. For Na the result is τ(3d Na)=19.27(23) ns.
