H2O-H2O collision rate coefficients

H2O-H2O collision cross sections are calculated by adapting the method deve loped by Anderson and Tsao and Cornette for the calculation of collision br oadening of molecular spectral lines. Cross sections are computed with a cu toff limit at 20 Angstrom(2) for the rotational levels of water with J less than or equal to 10 and E < 2000 cm-l in the temperature range 100-800 K. The accuracy of the calculated values is estimated to be 10%-20%.
