    Abstract:
    The axial CD spectra of single crystal of Zn(en)3(NO3)2 doped with 1‐50% Ni(en)3(NO3)2 have been observed at temperatures from ambient to 5 K. The increase in R of the 3E[3T3g(F)] transition as the temperature decreases is consistent with the magnetic dipole allowed character of the parent octahedral transition. The electric and magnetic dipole forbidden transition to the 3T1g(F) octahedral level gives rise to a relatively weak axial CD band with an unusual temperature dependent splitting. This structure is attributed to electric quadrupole intensity, which is allowed for transitions to both the E and 3A2[3T1g(F)] levels in D3 symmetry.
