摘要：

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°C to 25°C. Pure water vapor as well as air-broadened (N2/O2) 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 O2-broadened water vapor absorption as well as pure and air-broadened CO2 absorption. The CO2 data agree reasonably well with theoretical predictions; but the air- and O2-broadened water vapor data show greater absorption than theoretically predicted and seem to imply a super Lorentz/Voigt line shape for H2O. © 1979 Optical Society of America.
