Abstract
The effective rotational Hamiltonian for the stretching modes of H2X molecules have been analyzed on the base of the two conceptions: site-symmetry and linked groupings of vibrational rotational interactions. The site-symmetry of the effective Hamiltonian for the region of (v1, v3) dyad of H2X molecules at the condition mH << mx is reduced to Cs symmetry, as compared with C2V symmetry of the initial Hamiltonian. For the first time for H2X molecule with strong Coriolis-type accidental resonance it had been shown that the parameters of effective Hamiltonian depend on groupings of vibrational- rotational interactions. This dependence from weak via middle to strong resonances has the trend to decrease. For H2S molecule at the local mode limit, the effective Hamiltonian for Coriolis-type resonance don't depend on the groupings of initial Hamiltonian expansions. Two ways of experimental energy levels assignment for some vibrational polyads of H2S molecule, based on the symmetry reduction conception have been presented.
