Abstract

The reaction OH + NO 2 HNO 3 is a critical sink of HO x and NO x in the atmosphere. In addition to the stable molecule nitric acid, this reaction also produces the less stable HOONO molecule. The HOONO yield has been measured at room temperature and 20 torr. The yield of HOONO should increase with increasing pressure and decreasing pressure. As a result, it is critical to understand the HOONO yield under conditions relevant to the lower atmosphere. To this end, the yield of both HOONO and nitric acid from the reaction of OH + NO 2 were measured using IR-CRDS over a wide range of pressures. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
