An infrared Fourier transform spectrometer has been used with a long path length, multiple traversal cell to study the infrared spectra of atmospheric gases and several pollutant gases. Solar spectra have also been obtained between 3 and 20 micrometer wavelength. The kinetics of the formation and decay of nitrous acid have been followed by monitoring bands of nitric oxide, nitrogen dioxide, and both cis- and trans-nitrous acid. Rate constants and the equilibrium constant for the reactions have been derived. A mechanism accounting for the formation of nitrous acid in the atmosphere is proposed. These rate data have been used to speculate on the potential importance of nitrous acid formation in power plant and auto exhaust plumes. A new technique involving the use of infrared spectroscopy and two cells of unequal length to study a two-component system in equilibrium is described. A six-meter multiple traversal cell equipped with fluorescent tubes has been constructed. The cell irradiance closely simulates the solar irradiance at ground level in spectral distribution and intensity.
