Abstract
An optoacoustic detector or spectrophone has been used to perform detailed measurements of the absorptivity of mixtures of water vapor in air. A C12O216 laser was used as the source, and measurements were made. at forty-nine different wavelengths from 9.2 μm to 10.7 μm. The details of the optoacoustic detector and its calibration are presented, along with a discussion of its performance characteristics. The results of the measurements of water vapor absorption show that the continuum absorption in the wavelength range covered is 5–10% lower than previous measurements.Keywords
