Abstract The electrostatic and spin‐orbit matrices are calculated for spd configurations in LS ‐coupling using the sp ‐parent system. Diagonalizing the energy matrices by an electronic computer approximative eigenvectors in intermediate coupling for states of the configuration 5d6s6p in the lanthanum I‐spectrum were received. For the interpretation of several new hfs data obtained by levelcrossing – technique a compact formula for the quadrupole interaction in jj – coupling has been derived. In addition the complete quadrupole interaction matrices in LS ‐coupling for spd configurations are given including relativistic corrections. As an application the hfs interaction in the configuration 5d6s6p of the lanthanum I‐spectrum was discussed.
