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 dioxideCO2 as the reference.
