Abstract: | α-Al2O3 : Ti3+ (300 mass ppm concentration) at 10 K shows two electronic Raman transitions at 38 cm-1 and 109 cm-1. The E symmetry of the scattering matrix agrees with the selection rules for transitions between the ground state B and the E of the ground state manifold 2t2g.α-Al2o3 : V4+ shows two very weak electronic Raman transitions at about 30 cm-1 and 56 cm-1 respectively. |
