|Title:||Semi-Classical Line Shape Models of Rovibrational H2O Spectra Tested Using Frequency-Stabilized Cavity Ring-Down Spectroscopy|
|Published:||June 20, 2008|
|Abstract:||In this work we present a brief review of recent results for water line shapes obtained by means of the frequency stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We demonstrate its ability to enable precise spectroscopic measurements of absorption coefficients with high signal-to-noise ratio and high sensitivity as well as a well-determined spectrum frequency axis. Such high-fidelity measurements motivate the development of rigorous line shape models that allow to one to fit the observed spectra to within the statistical uncertainty. We show the impact of the choice of proper line shape models on the final result. Finally we make a few remarks about new efficient spectroscopic methods and their possible influence on molecular databases.|
