Abstract:

WN SOURCE OF ATMOSPHERIC HYDROGEN PEROXIDE, WHICH IS IMPORTANT IN THE CHEMISTRY OF ACID PRECIPITATION. DIRECT-MEASUREMENTS OF ATMOSPHERIC HYDROPEROXYL RADICAL CONCENTRATIONS PROVIDE IMPORTANT DATA FOR USE IN TESTING AND IMPROVING MODELS OF ATMOSPHERIC PHOTOCHEMISTRY. THE RESEARCH UTILIZES NEAR-INFRARED DIODE LASERS TO MEASURE TROPOSPHERIC HO2 CONCENTRATIONS BY ABSORPTION IN SPECTROSCOPIC BANDS NEAR 1500 NM. THIS APPROACH OFFERS IMPROVED SENSITIVITY, AS COMPARED TO MID-INFRARED METHODS, DUE TO THE HIGH POWER AND IMPROVED OPTICAL CHARACTERISTICS OF NEAR-INFRARED DIODE LASERS. LABORATORY EXPERIMENTS ARE BEING CONDUCTED TO MEASURE THE ABSORPTION CROSS SECTIONS OF HO2 NEAR 1500 NM. THE RESULTS OF THESE EXPERIMENTS PROVIDE A BASIS FOR CRITICAL ASSESSMENT OF THE FEASIBILITY OF THE TECHNIQUE FOR TROPOSPHERIC MEASUREMENTS.
