Using a 5-level model of an atom, I have identified the nature and determined the magnitude of the systematic errors in the frequencies of inelastic transitions among excited states measured by a fluorescence method. The errors arise because of describing the dynamics of the energy level population by use of models involving fewer number of the energy states (2, 3, and 4). It is shown that these errors may lead to reduction of the determined frequency by an order of magnitude in the region of high pressures. Two criteria for selection of an adequate model are given.
