High-resolution infrared spectroscopy of 15N216O in the 3500-9000 cm−1 region

The Fourier-transform absorption spectrum of 15N216O-enriched nitrous oxide has been recorded at the Doppler limited resolution in the spectral range 3500-9000 cm−1. 6523 Transitions of 15N216O 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 65 bands. Among these bands, 39 are newly observed, and the rotational analysis of 26 others were significantly extended and improved.
