Within the framework of quantum theory the radiationless phase relaxation of a molecular transition in a dense medium is described by an integro‐differential equation. From the Fourier transform of this equation formulas are derived for calculating the corresponding absorption profiles. For the case that the acoustic phonons of the medium are responsible for the phase relaxation a detailed discussion of the resulting absorption profiles is given.
