Global modeling of the 14N216O line positions within the framework of the non-polyad model of effective Hamiltonian

Abstract

The global modeling of 14N216O line positions in the 0.8–14,917 cm−1 region has been performed using the non-polyad model of effective Hamiltonian. The effective Hamiltonian parameters were fitted to the measured line positions collected from the literature. The dimensionless weighted standard deviation of the fit is 1.71. The fitted set of 195 effective Hamiltonian parameters allowed reproduction 56,888 measured line positions with an RMS value of 0.006 cm−1. Comparisons of the calculated line positions based on the fitted model with HITRAN2016 and a recent line list by Bertin et al. (J Quant Spectrosc Radiat Transf 2019;229:40–9) are presented and discussed.
