In this work, we study the single ionization of water molecules in liquid phase by fast electron impact. We employ a theoretical first-order model for computing multiple differential cross sections (MDCS) of ionization from the several initial water orbitals. These initial molecular states are represented through a Wannier orbital formalism. Coplanar geometries and asymmetric kinematic conditions are also considered. We find that our calculated MDCS averaged over all molecular orientations reproduce for each orbital the main physical features of the reaction.
