We present the results of our first-principles relativistic calculations of the fine-structure intervals and magnetic dipole transition probabilities for the 1{ital s}{sup 2}2{ital p} configuration of the lithium isoelectronic sequence using a variational approach. The contributions of the Breit interaction and approximate Lamb-shift corrections are incorporated via first-order perturbation theory. Our results of the fine-structure intervals are in good agreement with experiment, but experimental data for the magnetic dipole transition probabilities are not available for comparison with our calculations.
