Measurement of water vapor line strengths in the 1.4–2.7 µm range by tunable diode laser absorption spectroscopy

Autor: Andrea Pogány, Alexander Klein, Volker Ebert

Publikováno v: Journal of Quantitative Spectroscopy and Radiative Transfer. 165:108-122

Line strengths of nine water vapor absorption lines in the wavelength range between 1.37 and 2.71 µm with line strengths of 10 –23 –10 –20 cm/molecule have been measured using direct tunable diode laser absorption spectroscopy (dTDLAS). Four d

Optical Path Length Calibration: A Standard Approach for Use in Absorption Cell-Based IR-Spectrometric Gas Analysis

Autor: Andrea Pogány, Oliver Witzel, Volker Ebert, Olav Werhahn, Javis A. Nwaboh

Publikováno v: International Journal of Spectroscopy, Vol 2014 (2014)

We employed a comparison method to determine the optical path length of gas cells which can be used in spectroscopic setup based on laser absorption spectroscopy or FTIR. The method is based on absorption spectroscopy itself. A reference gas cell, wh
