Accurate calculations of the fine and hyperfine splitting of the 2P state in Li and Be+ isotopes using the explicitly correlated Hylleraas basis set are presented. Theoretical predictions including the mixing of P-1/2 and P-3/2 states, relativistic and quantum electrodynamic effects on hyperfine interactions, are compared with experimental values. It is concluded that precise spectroscopic determination of the nuclear magnetic moments requires elimination of nuclear structure effects by combining measurements for two different states.
