  Binding energies, quadrupole deformation parameters, spins and parities of
the neutron-deficient odd $Z=N+1$ nuclei in the $A\sim 80$ region are
calculated in the relativistic mean field approximation. The ground-state and
low-lying configurations of the recently observed $^{77}$Y, $^{79}$Zr and
$^{83}$Mo nuclei are analyzed. The calculated results are compared with other
theoretical predictions.
