摘要：

The absorption spectrum of single crystalline MnO has been measured at 1000-degrees-C as a function of oxygen partial pressure, p(O2). The observed p(O2)-dependence of the spectra is discussed in the framework of the point defect structure of the compound. From the line-shape of the defect-induced contribution to the absorbance and from its p(O2)-dependence it is concluded that this contribution is due to small-polaron hopping of electron holes.
