title: Water vapor absorption coefficients at HF laser wavelengths (2.64-2.93 microm).
abstract: Water vapor absorption coefficients are reported for nine HF laser wavelengths ranging from 3418.1600 cm(-1) to 3788.2253 cm(-1) for temperatures ranging from -18 degrees C to 25 degrees C. Pure water vapor as well as airbroadened (N(2)/O(2)) water vapor absorptions were measured at pressures from less than 1-764 Torr with some of the air-broadened data being used to extract effective self-to-foreign-broadening parameters in the vicinity of the laser frequencies. Limited data were also collected on O(2)-broadened water vapor absorption as well as pure and air-broadened CO(2) absorption. The CO(2) data agree reasonably well with theoretical predictions; but the air- and O(2)-broadened water vapor data show greater absorption than theoretically predicted and seem to imply a super Lorentz/Voigt line shape for H(2)O.
