Three luminescence bands in the yellow and red spectral region, which are related to the (1)Delta(g)(1)Delta(g) --> (3)Sigma(g)(- 3)Sigma(g)(-) double electronic transition of O-2, have been investigated in the alpha, beta, and gamma phase of solid oxygen. The temperature dependence of the intensity of the yellow band is strongly influenced by emission from higher vibrational levels of O-2((1)Delta(g)), which an populated by anharmonic V-V pumping. The broken mirror symmetry of the luminescence and absorption bands in the a phase of solid O-2 points to an interaction between the electrons and the elementary excitations of the crystal, which is different in the ground and excited electronic states, e.g., a quadratic electron-phonon interaction.
