Abstract

The global fitting of the experimental energy levels of unresolved Λ-doublets for the ground state of ¹⁴N¹⁶O molecule is done. The dataset of 1789 experimental energy levels covering the 0-35665 cm^-1 interval for 23 vibrational states was obtained using the fundamental Rydberg-Ritz combination principle. A global model of analysis with vibrational dependences of the parameters of the effective Hamiltonian was used for the theoretical treatment of the diatomic molecule in ²Π electronic state. As a result of the fit a set of the "Dunham-type" molecular parameters was obtained. They reproduce the dataset of the experimental energy levels to the precision of the experimental ones. The found set of the parameters was compared with previous set determined by C.Amiot.
