Parameters of the fine structure and coefficients of expansion of wave functions in the scheme of intermediate coupling in wave functions of the LS-coupling scheme are calculated semiempirically in the single-configuration approximation for the np2 configuration of a number of ions taking into account the electrostatic, spin-own orbit, spin-other orbit, spin-spin, and orbit-orbit interactions in the two-electron energy operator. The error of the calculation results is estimated.
