Abstract

The high resolution Fourier transform spectrum of the D2O (v = v1 + v2/2 + v3 = 3.5) polyad was analysed within the framework of the Hamiltonian model taking into account resonance interactions between the seven states (310), (211), (112), (013), (230), (131) and (032). Transitions belonging to the 2v1 + v2 + v3, 3v1 + v2 and 3v2 + 2v3 bands were assigned in the experimentally recorded spectrum. This provided the possibility of obtaining spectroscopic parameters of the 'visible' states (211), (310) and (032) and of estimating the band centres, and the rotational and resonance interaction parameters of the 'dark' states (112) and (131).
