The purpose of this paper is to make specific comparisons of two theoretical methods with available experimental measurements of H2O widths and shifts for the case of N2 or air broadening. The earliest calculations of H2O-n2 half widths were carried out by Benedict and Kaplan BK using the Anderson-Tsao-Curnutte ATC theory of pressure broadening. Considering that only one accurate measurement was available at the time their work was carried out, the theoretical results, with one notable exception, have stood up remarkably well.
