High-Resolution Continuum Source AAS: The Better Way to Do Atomic Absorption Spectrometry: Welz, Bernhard, Becker-Ross, Helmut, Florek, Stefan,

High--resolution continuum source atomic absorption spectrometry (HR--CS AAS) is the most revolutionary innovation since the introduction of AAS in 1955.

- "Infrared water vapor continuum absorption at atmospheric temperatures." Abstract Absolute absorption rates of pure water vapor and mixtures of water vapor and nitrogen have been measured in the laboratory at 350 GHz . The dependence on pressure and temperature has been obtained. Additionally, a water vapor continuum parameter estimation, taking even the previous laboratory measurements from 150 to 350 GHz into account, is performed. The water vapour continuum absorption in the atmospheric windows is certainly the absorption by far wings of these features. But it is hard to believe that far wings of water dimer bands, presumably detected in recent works by Paynter et al.

Continuum absorption

The absorption maximum lies around 603 nm, with a cross-section of 5.23 10 −21 cm 2. Continuum absorption by water vapour has the properties that it is much greater within water vapour bands and less between bands than the continuum implied by the Lorentz line shape applied to water monomer lines, which is derived from the clearly non-physical assumption that the collision time of the molecular interaction involved is instantaneous, i.e. the impact approximation. continuum absorption coefficienc and the elimination of thL atmospheric broadened continuum term..

The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point. It is shown that the continuum absorptions in four windows differ

The optical depths associated with Rayleigh scattering may also be computed. Abstract.

The MT_CKD continuum model includes continuum absorption due to water vapor, nitrogen, oxygen, carbon dioxide, and ozone. With respect to water vapor, the contributions of the foreign and self continuum are considered separately. The optical depths associated with Rayleigh scattering may also be computed.

The dependence on pressure and temperature has been obtained.
