The ionization of the H2O molecule in intense ultrashort electric fields was studied theoretically. Ionization probability densities were calculated using classical and quantum mechanical approaches. The water molecule is treated within the hydrogenic approximation. Classical calculations were carried out using the classical trajectory Monte Carlo method, while quantum mechanical calculations are based on the sudden strong field approximation. A good agreement between classical and quantum calculations was found.
