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.
报告了温度范围为-18℃至25℃时，九个HF激光波长（范围从3418.1600厘米⁻¹至3788.2253厘米⁻¹）的水蒸气吸收系数。在压力小于1至764托的情况下，测量了纯水蒸气以及空气加宽（N₂/O₂）的水蒸气吸收，部分空气加宽数据用于提取激光频率附近的有效自加宽与外来加宽参数。还收集了有限的关于O₂加宽的水蒸气吸收以及纯的和空气加宽的CO₂吸收的数据。CO₂数据与理论预测相当吻合；但空气和O₂加宽的水蒸气数据显示出比理论预测更大的吸收，似乎暗示了H₂O的超洛伦兹/佛克脱线型。
