Raman scattering cross‐sections for tunneling transitions of diatomic molecular or off‐center defects in cubically symmetric environments are derived for 〈100〉, 〈111〉, and 〈110〉 defects for arbitrary scattering geometry. These cross‐sections are expressed in terms of the anisotropic electronic polarizability components of the defect.
