The density of valence states of the II‐VI compounds ZnSe, CdS, and HgS has been determined with far uv ( h v = 21.1 and 40.8 eV) photoemission. Discrepancies in the widths of the top portions of the valence bands between theory and experiment, similar to those reported for other II‐VI compounds in part I, are also found here. The results for ZnSe are compared to those obtained by others using synchrotron radiation and monochromatized X‐rays.
