## 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 ringโdown spectroscopy (CRDS) detection of NO~3~ radicals at 662 nm. The Arrhenius expression of the thermal

Diode laser cavity ring-down spectroscopy (CRDS) has been used to measure rotational line intensities and air pressure broadening coefficients for the 3m 3 (N-N stretching) vibrational overtone band of N 2 O. The line intensity measurements are in quantitative agreement with previously reported Four
The Fourier transform Raman spectra of the fundamental bands of 14 N 15 N and 15 N 2 were measured with a resolution of 0.02 cm -1 . Lines from all branches (O, Q, S) were observed and measured. The analyses of the wavenumbers yield improved values for the band origins n 0 . 14 N 15 N/ = 2291.33773.
Cavity ring-down (CRD) techniques were used to study the kinetics of the reaction of Br atoms with ozone in 1-205 Torr of either N 2 or O 2 , diluent at 298 K.
