Vibronic structure in the circular dichroism of transition metal complexes
Abstract
Vibronic structure observed in the circular dichroism of (+)[Co(en)3]3+ and α-Ni(H2O)6SO4 is analyzed in terms of the theory of Weigang. The rotational strength of the magnetic dipole allowed 1A1(1A1g)→1E(1T1g) transition of (+)[Co(en)3]3+ is predominantly static in origin, whereas that of the magnetic dipole forbidden 3A2g→3aT1g transition of α-Ni(H2O)6SO4 is predominantly vibronic in origin.
