We present a detailed study of the ionization probability of H2 O induced by a short intense laser pulse. Within the strong-field approximation, we present total and differential ionization probabilities of the water molecule fixed in space. It is shown that the second highest occupied molecular orbital (HOMO-1) dominates the single-electron emission process when the laser is polarized along the symmetry axis of the H2 O molecule, and that the electron emission is in general favoured in the direction along the laser polarization direction.
