FAR-INFRARED EMISSION-SPECTRA FROM STRATOSPHERIC HYDROGEN-PEROXIDE

Synthetic emission spectra from two stratospheric altitude observation s have been analyzed for the presence of H2O2 in the far infrared regi on. The calculations are made with a high spectral resolution (10(-3) cm(-1) or 10(-4) cm(-1)) greater than those in experimental measuremen ts which are in the region of 3.10(-3) cm(-1). Spectra cover a spectra l interval between 40 and 120 cm(-1) showing the best features of H2O2 susceptible to observation in a stratospheric spectrum. The optimum c onditions for identification have been considered. Using the variation s in H2O2 abundance in the measurement data and photochemical models, the H2O2 features detection limits have been studied.
