    "abstract": "State-dependent quantum electrodynamic corrections are evaluated for the\nhyperfine splitting of nS states for arbitrary principal quantum number n. The\ncalculations comprise both the self-energy and the vacuum-polarization\ncorrection of order alpha(Z alpha)^2 E_F and the recoil correction of order (Z\nalpha)^2 (m/M) E_F. Higher-order corrections are summarized and partly\nreevaluated as well. Accurate predictions for hydrogen hyperfine splitting\nintervals of nS states with n=2,...,8 are presented. The results obtained are\nimportant due to steady progress in hydrogen spectroscopy for transitions\ninvolving highly excited S states.",
