Water vapor continuum absorption in the 2.7 and 6.25 μm bands at decreased temperatures


High-resolution Fourier transform spectroscopy laboratory measurements of pure water vapor absorption have been performed for the first time at temperatures from–9 to 15°С in the near-IR spectral region. As the result, the water vapor continuum absorption is retrieved within 1600 and 3600 cm–1 absorption bands (6.25 and 2.7 μm, respectively). Spectral features of the continuum retrieved at 15°С are in good agreement with the known data. It is shown that different spectral peaks of the continuum have different temperature dependencies.
