Abstract

The thermal decomposition rate of N~2~O~5~ in 760 Torr of air as a function of temperature between 314 and 348 K has been investigated using the technique of pulsed laser cavity ring‐down spectroscopy (CRDS) detection of NO~3~ radicals at 662 nm. The Arrhenius expression of the thermal decomposition rates determined by the CRDS experiments, which is incorporated with literature values down to 263 K, is given by 1.36 × 10^15^ exp{(−11300 ± 200)/T} s^−1^ over the temperature range 263–348 K. © 2008 Wiley Periodicals, Inc.
