The theory of the one‐phonon sidebands of zero‐phonon optical transitions has been developed for the long wavelength acoustical phonons. In this theory the phenomenological parameters representing the electron–phonon interactions are expressed in terms of the spectral shifts of the zero‐phonon transitions induced by uniaxial stress. Means of extending the theory to other phonon branches and wavelengths are discussed and application to the 9,570 cm −1 aggregate defect center in neutron irradiated MgO is given.
