Abstract: | The phonon sidebands on the excitons observed in certain molecular crystals may be represented by a weighted density of states. It is here shown qualitatively and by reference to typical experiments that this function does not, in general, resemble the true density of states but often may be predicted from data on the Brillouin zone centre translational modes. |
