The influence of the Doppler differential effect on the hydrogen spectrum in an atmosphere where velocity fields exist (expansion, contraction, and rotation) is investigated using Sobolev's method as modified by Castor (1970). Consideration is given to the geometry and physical conditions of the emitting regions, statistical equilibrium and energy balance equations, and the observed spectra. It is shown that the introduction of the Doppler differential effect in the interpretation of Seyfert I galaxies and quasars spectra explains the observed relative intensities of the H I lines in terms of a simplified photoionized model (PR + PTR) of the broad line region.
