Photoelectric yield and energy distribution curves for photon energies up to 11 eV, have been studied for evaporated sulphur films. For clean films the threshold occurs at 7.2 eV. The EDC's, as well as the form of the yield near threshold, agree well with calculated curves derived from the molecular orbital calculation of Chen, with levels broadened by taking into account intermolecular interactions.
