The 1s22s22p2P ground state and the 1s22s2np (n = 3, 4) 2P, 1s22s23s2S, 1s22s2p24P, 2L (L = S, P, D), 1s22s2p3s4Po, 1s22s2p3p4S, and 1s22p34S o , 2Lo (L = P, D) excited states of boron are calculated using the Rayleigh-Ritz variational method with multiconfiguration interaction wave functions. Energies, expectation values such as the electron density at the nucleus ρ(0) and radial moments ⟨ rn ⟩, and fine-structure splittings are calculated. Hyperfine structure parameters and magnetic coupling constants of these states are also calculated. The present results are in good agreement with theoretical and experimental data available in the literature and should provide valuable reference data for future theoretical calculations and experimental measurements.
