We study the single ionization of water molecules in liquid phase by fast electron impact. We have developed a theoretical model based on the first Born approximation for computing multiple differential cross sections of ionization from the several orbitals. The initial molecular state is represented through a Wannier orbital formalism. Coplanar geometries and asymmetric kinematic conditions are considered. Our computed cross sections averaged over all molecular orientations reproduce for each orbital the main physical features of the reaction.
