MCD of the Eu3+ ion in aqueous solution. Analysis of the 5D0,1,2←7F0,1,2 transitions

Abstract
An electric or magnetic dipole character is assigned to the transitions in the visible region of the Eu3+absorptionspectrum. The theoretical calculation of the sign properties of the corresponding Faraday parameters is supported by the experimental MCD of the aqueous solution. It is shown that the magnetic circular dichroism of all the considered transitions points to a D 3h symmetry of the hydrated Eu3+ ion.
