Abstract

The ⁴A_2g -> ⁴T_2g zero-phonon spectrum of Cr³⁺ in MgO is interpreted by a Jahn-Teller effect with e_g modes and coupling with a_1g modes. It is shown that the mixing between ⁴T₂ zero-phonon levels and ²E, ²T₁ vibronic levels by spin-orbit interaction is determined for this spectrum.

Structure of the 4A2g -> 4T2g zero-phonon spectrum in MgO:Cr3+. Spin-orbit and vibronic couplings

The 4A2g -> 4T2g zero-phonon spectrum of Cr3+ in MgO is interpreted by a Jahn-Teller effect with eg modes and coupling with a1g modes. It is shown that the mixing between 4T2 zero-phonon levels and 2E, 2T1 vibronic levels by spin-orbit interaction is determined for this spectrum.
