High-resolution Infrared Spectroscopy of ¹⁵N₂¹⁶O in 1650-3450 cm^-1

High-resolution ro-vibrational spectroscopy of ¹⁵N₂¹⁶O in 1650-3450 cm^-1 region is studied using highly enriched isotopologue sample. The positions of more than 7300 lines of ¹⁵N₂¹⁶O isotopologue were measured with a typical accuracy of 5.0×10^-4 cm^-1. The transitions were rovibrationally assigned on the basis of the global effective Hamiltonian model. The band by band analysis allowed for the determination of the rovibrational parameters of a total of 73 bands. 29 of them are newly reported and more rotational transitions have been observed for the others. The maximum deviation of the preidictions of the effective Hamiltonian model is up to 0.70 cm^-1 for the ¹⁵N₂¹⁶O species.
