Phillips, T.R., S. Maluendes, and S. Green, 1996: Collisional excitation of H₂O by H₂ molecules. Astrophys. J. Supp. Ser., 107, 467-474, doi:10.1086/192372.

Using an accurate theoretical rigid-rotor interaction potential for H₂O-H₂ and accurate coupled channel molecular scattering calculations, rates have been obtained for excitation of para- and ortho-water out of the lowest, j = 0, 1, and 2, rotational levels owing to collisions with para- and ortho-H₂ at kinetic temperatures from 20 K to 140 K. Excitation by para-H₂ is not too different from excitation by He atoms, with most rates being within a factor of 1-3 larger, but excitation by ortho-H₂ is significantly different, with some rates an order of magnitude larger than rates for excitation by He atoms.
