A theoretical study for the ionization from several orbitals of the water molecules in liquid phase by electron impact is presented. Multiple differential cross sections are computed through a first order model considering an asymmetric coplanar geometry. The wavefunctions for a single liquid water molecule are obtained in a realistic way by using a Wannier orbital formalism. The comparison with previous theoretical results as well as experiments for the gas phase shows a qualitative agreement. Moreover, an analysis of the influence of the passive electrons is performed by the assistance of different static potentials.
