Abstract

Abstract : Water vapor continuum absorption was measured in the 900-1050/cm region using tunable diode laser and a 1-M base White cell at 296 K and 337 K. Both continuous and spot frequency absorption show pressure squared dependence. The high resolution technique takes into account local line absorption very well in determining the continuum absorption. Results show a slightly weaker temperature dependence for the continuum absorption. A proposed double resonance spectroscopic technique is described in which a CO laser in coincidence with a water vapor line is used to pump the water vapor transition and a CW Tunable Diode Laser is used to probe the water vapor absorption coefficient up to 100 halfwidths from the pressure broadened line to determine the lineshape.
