摘要
We present and discuss experimental and theoretical relevant intensity parameters of 4f-4f transitions in the Eu(dipivaloylmethanate)(3) 1,10-phenanthroline complex which is a highly luminescent material under UV excitation. The theoretical analysis is based on; the crystallographic data of the compound and on a theoretical scheme which lakes into account the forced electric dipole and dynamic coupling mechanisms as developed in previous work. The good agreement found between theory and experiment provides support to the model used and indicates that, at least in the present case, further contributions to the intensities beyond the second-order theory are of no relevance.
