  We obtain continuum molecular wavefunctions for open-shell molecules in the
Hartree-Fock framework. We do so while accounting for the singlet or triplet
total spin symmetry of the molecular ion, that is, of the open-shell orbital
and the initial orbital where the electron ionizes from. Using these continuum
wavefunctions, we obtain the dipole matrix elements for a core electron that
ionizes due to single-photon absorption by a linearly polarized X-ray pulse.
After ionization from the X-ray pulse, we control or streak the electron
dynamics using a circularly polarized infrared (IR) pulse. For a high intensity
IR pulse and photon energies of the X-ray pulse close to the ionization
threshold of the $1{\sigma}$ or $2{\sigma}$ orbitals, we achieve control of the
angle of escape of the ionizing electron by varying the phase delay between the
X-ray and IR pulses. For a low intensity IR pulse, we obtain final electron
momenta distributions on the plane of the IR pulse and we find that many
features of these distributions correspond to the angular patterns of electron
escape solely due to the X-ray pulse.
