An atlas of observed and calculated air spectra from 700 to 2300/cm has been prepared. Methods of analyzing air spectra to identify spectral features and to determine simultaneously the abundances of atmospheric gases such as CO, N2O, CH4, O3, H2O, and CO2 have been explored. These methods include ratioing observed and calculated spectra and correlation analysis of absorption bands to obtain abundances by linear regression and nonlinear least squares methods. Absorbing features of atmospheric gases such as O3, H2O, and N2O have been removed from solar spectra to isolate underlying features of F-12 near 1160/cm. Simulations of the reactions in a typical NOX-RH-RCHO-polluted atmosphere exposed to sunlight show that the theoretical rate of HO2NO2 generation is similar in magnitude to those expected (and observed in real atmospheres) for peroxyacylnitrates.
