The electric-field-dependent $g$ factor and the electron electric dipole moment (eEDM)-induced Stark splittings for the lowest rotational levels of ${}^{207,208}\mathrm{PbF}$ are calculated. Observed and calculated Zeeman shifts for ${}^{207}\mathrm{PbF}$ are found to be in very good agreement. It is shown that the ${}^{207}\mathrm{PbF}$ hyperfine sublevels provide a promising system for the eEDM search and related experiments.
