The non-relativistic energies of the excited states 1s2nl (l = 4, 5) with high angular momentum of the lithium-like systems from Z=3 to 5 are calculated by using a full-core plus correlation method with multi-configuration wave functions. Relativistic and mass-polarization effects on the energy are evaluated perturbatively as the first corrections. Their fine structures are calculated by using spin-orbit and spin-other-orbit interaction operators. Our results follow a well isoelectronic behavior.
