Raman Spectra and Cross Sections of Ammonia, Chlorine, Hydrogen Sulfide, Phosgene, and Sulfur Dioxide Toxic Gases in the Fingerprint Region 400-1400 cm-1

Abstract

The Raman spectra and cross sections of toxic gases are important for the detection of these gases using Raman spectroscopy in the fingerprint region 4001400 cm-1. Raman cross sections of a number of gases (CH4, C2H6, C3H8, C6H6, CO,CO2, F2, HBr, HCl, HF, H2, H2O, H2S, N2, NH3, ND3, NO, N2O, O2, O3, and SO2) have been reported previously.16 In this paper, we report the measurement of the Raman spectra and cross sections of ammonia (NH3), chlorine (Cl2), hydrogen sulfide (H2S),phosgene (CCl2O), and sulfur dioxide (SO2) toxic gases in the fingerprint region 4001400 cm1 using the Raman cross section of the 1285 cm1 mode of carbon dioxide(CO2) as the reference.
