NOSD-1000, the high-temperature nitrous oxide spectroscopic databank

- NOSD-1000 is aimed at high temperature applications.
- NOSD-1000 contains 14N216O data.
- NOSD-1000 is based on global fits of measured line positions and intensities.
- NOSD-1000 contains calculated line parameters for the 260-8310 cm−1 spectral range.

We present a high-temperature version, NOSD-1000, of the nitrous oxide spectroscopic databank. The databank contains the line parameters (positions, intensities, air- and self-broadened half-widths and coefficients of temperature dependence of air- and self-broadened half-widths) of the most abundant isotopologue 14N216O of the nitrous oxide molecule. The reference temperature is Tref=1000 K and the intensity cutoff is Icut=10−25 cm−1/(molecule cm−2). More than 1.4 million lines covering the 260-8310 cm−1 spectral range are included in NOSD-1000. The databank has been generated within the framework of the method of effective operators and based on the global fittings of spectroscopic parameters (parameters of the effective Hamiltonian and effective dipole moment operators) to observed data collected from the literature. Line-by-line simulation of a medium-resolution high-temperature (T=873 K) spectrum has been performed in order to validate the databank. NOSD-1000 is freely accessible via the Internet.
