Study of kinetics of the singlet and triplet states population of hydrogen molecule is directly connected with the justification of diagnostics of nonequilibrium plasma by the method of optical emission spectroscopy. We briefly consider the approach to the zero-dimension hydrogen collision-radiative model, which in addition to kinetic models of vibrational states population kinetics of hydrogen molecule. The model is based on the analysis of a large number of known experimental data which, among other things, are used to verify the model. The model was used for investigating the possibility of using emission of triplet hydrogen states for diagnostics of nonequilibrium DC discharges, microwave discharges, and ECR discharge. In particular, the limitations are shown on the applicability of the simplified coronal plasma model for the diagnostics of these discharges by the frequently used emission of the Fulcher system bands.
