The role of the interaction with the nearest electronic state {sup 3{Sigma}}{sub 0}{sup -+} on the hyperfine structure and magnetic properties of the a(1)[{sup 3{Sigma}}{sub 1}{sup +}] state of PbO is assessed. The accounting for this contribution leads to the difference between g factors of the J=1 {Omega}-doublet levels {Delta}g=37x10{sup -4}, which is in good agreement with the experimental data {Delta}g=30(8)x10{sup -4}. The contribution of this interaction rapidly grows with J. For J=30, the difference of g factors of {Omega}-doublet states reaches 100%; for hyperfine constants, it reaches 18%. These differences also depend on the electric field, and, for E=11 V/cm for {sup 207}PbO, the difference in g factors turns to zero. The latter is important for suppressing systematic effects in the electron electric dipole moment search experiment.
