Abstract

Experiments have been carried out in a large stainless steel reaction vessel to investigate the rate of homogeneous production of nitrous acid, HONO, from the reaction of HO₂ radicals with NO₂: HO₂ + NO₂ → HONO + O₂. The product distribution was determined using Fourier transform infrared (FTIR) spectrometry. No evidence for the reaction was found, and an upper limit for the rate coefficient of 5 X 10^-16 cm³ molecule^-1 s^-1 was derived. This value is small enough to exclude the reaction from being a significant source of nitrous acid in the atmosphere.
