The interaction between the H2O molecule and intense ultrashort laser pulses is theoretically studied. Ionization probability densities are calculated using classical and quantum mechanical models. Single active electron calculations were performed within the hydrogenic approximation along with calculations using multicenter model potential for the molecular Coulomb potential. Significant difference between the results obtained with the hydrogenic approximation and with the multicenter potential were observed.2O molecule and intense ultrashort laser pulses is theoretically studied.
