  Time-delays in the photoionization of molecules are investigated. As compared
to atomic ionization, the time-delays expected from molecular ionization
present a much richer phenomenon, with a strong spatial dependence due to the
anisotropic nature of the molecular scattering potential. We investigate this
from a scattering theory perspective, and make use of molecular photoionization
calculations to examine this effect in representative homonuclear and
hetronuclear diatomic molecules, nitrogen and carbon monoxide. We present
energy and angle-resolved maps of the Wigner delay time for single-photon
valence ionization, and discuss the possibilities for experimental
measurements.
