Abstract

This work is devoted to the investigation of the influence of intramolecular effects on the relaxation parameters of H₂O molecule spectral lines in 3ν₁+ ν₃ band. H2O-N2 halfwidths and lineshifts are calculated in the framework of semiclassical impact theory. Dipole-quadrupole and polarization interactions were taken into account. Calculated H₂O-N₂ halfwidths and lineshifts are compared with experimental one. The differences between the halfwidths and lineshifts calculated using both traditional Watson hamiltonian and Pade-Borel transformed hamiltonian are analysed.
