Abstract:

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

Keywords:

continuum absorption, water vapour, near-IR absorption bands
