Fourier-transform spectroscopy of 15N14N16O in the 3500-9000 cm−1 region

The Fourier-transform absorption spectrum of 15N14N16O-enriched nitrous oxide has been recorded at the Doppler limited resolution in the spectral range 3500-9000 cm−1. More than 15 000 transitions of 15N14N16O were observed and assigned based on the global effective Hamiltonian model. The band-by-band analysis led to the determination of the ro-vibrational parameters of a total of 133 bands. Among these bands, 103 were newly observed, and the rotational analysis of 30 others were significantly extended and improved.
