Paper Abstract

The pressure-broadening of the 3(1,3) - 2(2,0) and 4(1,3) -3(2,1) transitions of water at 183 and 380 GHz respectively, were studied over a wide temperature range. These included broadening by 02, N2, He, and H2 with the temperature dependence between 80K and 600K. Low temperature measurements were taken in a collisionally cooled cell with variable temperature injectors. Results for the temperature dependence of the pressure broadening parameters are compared with theoretical calculations and with experimental values of other researchers.
