The Zeeman spectra of the neutral acceptor Zn–H in Ge have been studied in the Voigt geometry with B along the three principal crystallographic directions 〈100〉, 〈111〉 and 〈110〉 using plane‐polarized radiation with the samples held near 4.2 K. The results for B ∥ 〈111〉 are described in detail. The interpretation of the data supports the model proposed for this complex, viz., that the axis is along a 〈111〉 bond direction of the host. This lowers the symmetry of the hole states resulting in a split ground state consisting of two Kramers' doublets. These are sufficiently separated in energy for the upper one to be depopulated at the sample temperatures used. The spectra provide a “template” for the identification of other such complexes.
