  "abstract": "The new approach is develop to determine the hyperfine structure of the rotationally excited $1 s_μ n \\ell_{e}$-states in the three-body helium muonic ${}^{3}$He $μ\\; e$ and ${}^{4}$He $μ\\; e$ atoms. The formulas derived in this study allow one to evaluate the hyperfine structure splittings for an arbitrary rotationally excited (bound) $1 s_μ n \\ell_{e}$-state in the three-body helium muonic atoms. Similar formulas have never been produced in earlier studies and this explains why these hyperfine structure splittings are still unknown for these bound states.",
