Line strength and collisional broadening studies of hydrogen sulphide in the 1.58 mu m region using diode laser spectroscopy

Abstract:

High resolution diode laser spectroscopy has been applied to the detection of hydrogen sulphide at ppm levels utilizing different transitions within the region of the ν 1+ν 2+ν 3 and 2ν 1+ν 2 combination bands around 1.58 μm. Suitable lines in this spectral region have been identified, and absolute absorption cross sections have been determined through single-pass absorption spectroscopy and confirmed in the Doppler linewidth regime using cavity enhanced absorption spectroscopy (CEAS). The de...
