Green, S., 1980: Collisional excitation of interstellar molecules: Water. Astrophys. J. Supp. Series, 42, 103-141, doi:10.1086/190646.

Rate constants for excitation of water molecules by collisions with He atoms have been obtained from extensive theoretical calculations. For ortho-H2O, rates are presented for all spectroscopic levels below 1000 /cm and for kinetic temperatures to 500 K; for para-H2O, levels below 300 /cm and kinetic temperatures to 250 K are included. It is suggested that rates of excitation by collisions with hydrogen molecules are similar to those for He atoms.
