We present a theoretical calculation of the fine and hyperfine splittings of the energy levels in the metastable states of antiprotonic helium ${}^{4}{\mathrm{He}}^{+}\overline{p},$ performed with the accuracy of ${10}^{\ensuremath{-}4}.$ We also discuss the perspectives of obtaining experimental data on the magnetic moment of the antiproton from measurements of the hyperfine structure of antiprotonic helium.
