Parameters of the effective vibrational Hamiltonian of the H2S molecule are derived using an extended experimental data set. The Darling-Dennison and weak Fermi-type resonance interactions were taken into account in the effective Hamiltonian. As a result of fitting to 52 experimental band origins, 25 vibrational constants were derived, which reproduce the initial data accurate to 0.03 cm-1.
