From a non-stationary Schrödinger equation in an adiabatic approximation the analytical expressions for the probabilities of transition under the influence of electromagnetic radiation in a three-level quantum system are obtained, the energy position of whose levels varies in time according to the harmonic law. The influence of a lifetime and amplitude of modulation of the levels position on their population dynamics and spectral distribution of a low-frequency response of the system is explored.
