Abstract
N2-broadened halfwidths for the pure rotation band of H2O have been calculated for some 1600 transitions using quantum Fourier transform (QFT) theory. The QFT method corresponds to a quantum mechanical second-order perturbation development of collisional broadening within the binary collision approximation. Self-broadened halfwidths as well as pressure shifts were also calculated in this study but are not presented here. The N2-broadened halfwidths were used to form the data base of H2O halfwidths present on the AFGL main gas Atlas and replace the earlier Anderson calculations by Benedict and Kaplan.
