Absorption coefficients are measured at CO and CO2 laser wavelengths for the poison gas phosgene, CCl2O, and the isotopic species H216O, H218O, HD16O, D216O, 14N16O, and 15N16O. The laser lines selected are those in near coincidence with absorption lines of the gases and vapors studied. These data should prove useful in analytical applications relating to pollution monitoring and control of phosgene or D2O leaks. They also demonstrate the feasibility of determining certain important isotope abundances or ratios by simple and rapid infrared spectroscopic methods.
