The matrices of spin-orbit interaction in the p  2  d and p  4  d electron configurations have been calculated in the LS representation. The matrices have been checked by showing that their eigenvalues, calculated by use of an IBM 7090, agree with the correct eigenvalues known from the theory of jj -coupling. For the sake of completeness, the energies of electrostatic interaction for these configurations are also given.
