Abstract

The kinetics of the gas‐phase reaction of the NO~3~ radical with naphthalene have been investigated at 150 torr O~2~ + 590 torr N~2~ and 600 torr O~2~ + 140 torr N~2~ at 298 ± 2 K. Relative rate measurements were carried out in reacting NO~3~N~2~O~5~‐naphthalene‐propene‐O~2~N~2~ mixtures by longpath Fourier transform infrared absorption spectroscopy. A rate constant ratio for the reactions of O~2~ and NO~2~ with the NO~3~‐naphthalene adduct of k/k < 4 × 10^−7^ was obtained from the competition between O~2~ and NO~2~ for reaction with the NO~3~‐naphthalene adduct and thermal decomposition of the adduct back to reactants. Atmospheric pressure ionization MS/MS measurements of the nitronaphthalene products of the NO~3~ radical‐initiated reaction of naphthalene are consistent with the proposed reaction mechanism, and the atmospheric implications of the data are discussed. © 1994 John Wiley & Sons, Inc.
