— Further evidence is found that acetophenone in its triplet‐state is formed as the luminescent species in the autoxidation of ethylbenzene. Energy transfer from this ketone to the triplet‐states of various acceptors results in quenching of the already weak chemilumin‐escence and follows a diffusion‐controlled rate as expected. The poor resemblance between the experimentally recorded spectral distribution of this light emission and the known phosphorescence spectra of the assumed emitters is discussed.
