The case of temperature quenching of luminescence of broad‐band emitters is examined. On the basis of published and newly acquired data, it is concluded that the theory of nonradiative transitions based on coupling to a single vibrational mode, whether calculated in the Mott‐Seitz terms or improved by the procedures developed by Struck and Fonger, is totally incapable of accounting for observed radiationless rates. There is no evidence for the operation of selection rules for nonradiative transitions.
