“…The fixed bond lengths are 2.18 a 0 for NN and 2.17 a 0 for NO. This corresponds essentially to shifting the central atom by 0.06 a 0 towards the oxygen atom, as compared to the experimental geometry 8 and yields a dipole moment of 0.07 au (0.17 D, O being the negative pole, exp. 9 0.167 D) and a quadrupole moment of À2.85 au.…”

“…We then detected the double labeled 15 N 15 NO molecule, using spectral line positions reported previously [19]. Although the branching ratio into (9a) is modest, N 2 O is a very strong infrared absorber, so this experiment has a reasonably low detection limit.…”

IR diode laser spectroscopy was used to detect the products of HCNO (fulminic acid) photolysis at 193 nm. Six product channels are energetically possible at this photolysis wavelength: O + HCN, H + NCO/CNO, CN + OH, CO + NH, NO + CH and HNCO. In some experiments, isotopically labeled 15 N 18 O, C 2 D 6 or C 6 H 12 reagents were included into the photolysis mixture in order to suppress and/or redirect possible secondary reactions. HCN, OC 18 O, 15 N 15 NO, CO, DCN and HNCO molecules were detected upon laser photolysis of HCNO/reagents/buffer gas mixtures. Analysis of the yields of product molecules leads to the following photolysis quantum yields: φ 1a (O+HCN) = 0.38 ± 0.04, φ 1b (H + (NCO)) = 0.07 ± 0.02, φ 1c (CN + OH) = 0.24 ± 0.03, φ 1d (CO + NH(a 1 ∆)) < 0.22 ± 0.1, φ 1e (HNCO) = 0.02 ± 0.01 and φ 1f (CH + NO) = 0.21 ± 0.1, respectively.

“…However, to be applicable for the S‐branch, the Q‐branch coefficients were processed according to a sum‐rule, Γ S J , J+ 2 = (Γ Q J,J + Γ Q J+ 2, J+ 2 )/2, which is considered a valid approximation . The internuclear distances, r (N–N) and r (N–O) , were collected from the work of Plíva . Analogous to the rotational CO 2 CARS code, the rule stating that only J ≥ l is allowed for bending modes has been neglected for simplicity, and the correction of the Placzek–Teller coefficient with respect to the quantum number l has been accounted for.…”

Pure rotational coherent anti-Stokes Raman scattering (CARS) spectra of N 2 O was recorded in a series of temperature calibrated cell measurements in the region 295-796 K. A theoretical rotational CARS code for N 2 O was implemented and temperature analysis was performed by fitting the modeled theoretical spectra to the experimental spectra. Excellent agreement between the experimental and modeled spectra was obtained and the thermometric accuracy for the measurements was evaluated to be better than 1%. Also, rotational N 2 CARS spectra were recorded at the same measurement conditions and the temperature analysis performed on these spectra resulted in the same accuracy. The peak signal strength was found to be~5 times stronger for N 2 O than for N 2 at ambient temperature and pressure. The temperature precision was evaluated to a relative standard deviation of 2.0%-2.7% in the studied temperature range, about half of the values for N 2 , which is attributed to the larger number of spectral lines for N 2 O. Rotational N 2 O CARS thermometry show great potential, because of a high Raman cross-section and large number of populated rotational states at any temperature.
