Polarization spectra covering infrared, visible and ultraviolet ranges from 2200-27000 cm-1 have been obtained of enstatite at room and liquid helium temperatures. The main features of these spectra are described in terms of a set of assignments of crystal field levels and a theory of intensities which involves the mixing of a charge transfer state into the 3d6 states of the ferrous ion. This better accounts for the features of the polarized absorption spectra of ferrous ion in pyroxenes than do the explanations of Bancroft and Burns (1967) and White and Keester (1967).
