Abstract: This paper reports a theoretical study of photoionization in a gaseous C 3v molecule prepared in a single rotational state of its ground electronic motion by an electrostatic hexapole field and oriented in space by the subsequent application of a weak homogeneous electric field . Markedly different cross-sections are calculated for electrons ejected from 13a2 1 orbital of a molecule by electromagnetic radiation plane polarized parallel and perpendicular to . These photocurrents change further in different manners with rotational states of . In accord with the experimental observation by Kaesdorf [Phys. Rev. Lett. 54, 885 (1985)], we also find a pronounced asymmetry in the photocurrents emitted in directions along and opposite to . This forward - backward asymmetry, which very strongly depends upon the rotational state of the molecule, is however more pronounced in parallel than in perpendicular experimental geometry. Both circular as well as linear dichroisms have also been studied, but neither of these shows any forward-backward asymmetry in the present application.
