The rotational properties of $A=7, 9, 11, \mathrm{and} 13$ nuclei are studied in a self-consistent way using the effective two-body interactions derived either from the Sussex relative harmonic-oscillator matrix elements or from energy-level fitting. Special care is taken in choosing the appropriate solution among others corresponding to oblate or prolate deformed orbitals. In particular, a pronounced band mixing in $A=9\mathrm{}$ and $A=11\mathrm{}$ nuclei is investigated by diagonalizing the effective Hamiltonian within the orthonormalized basis setup with the Hartree-Fock projected states. Moments of inerita of $A=6, 8, 10, \mathrm{and} 12$ nuclei are also computed by means of the cranking model. The energy levels and the magnetic dipole moments, as well as the $M1\mathrm{}$ transition rates, are in good agreement with shell-model calculations which use the same effective two-body interactions.
