We have performed semi-empirical calculations on a Eu(III)-imidazole comple
x. We use a Scaled Quantum Mechanical Force field approach from the MOPAC s
oftware. We obtain molecular force constants used in the normal mode calcul
ation to modelize experimental Raman frequencies. Furthermore, we discuss t
he structure and the electronic properties of this complex by means of spec
troscopic techniques such as photoluminescence and X-Ray Absorption Near-ed
ge Spectroscopy (XANES).
