f–f Transition intensities of europium(III) acetate complexes in a single crystal and in solution

electric dipole transitions; old problems in a new light

“…1, where the quality of the results of numerical calculations are presented for various transitions observed in the Eu 3+ ion in an acetate crystal [20]. In the figure not the actual values of the intensities of the appropriate transitions are presented, but rather the errors of reproduction defined as follows,…”

“…Relative errors of reproduction of the intensity of f ↔ f transitions observed in the Eu 3+ ion in an acetate crystal[11,20].…”

Magnetic dipole transitions in crystals

“…It is seen in Table 1 that in the case of the 7 F 1 → 5 D 0 and 5 F 0 → 5 D 1 lines observed for europium ion in acetate crystal, the value of P MD is larger than the P exp which is taken from [22]. This can be considered as a result of the overestimation in crude calculations.…”

“…In Table 1 the observed oscillator strengths P exp for certain transitions are taken from Ref. [22] and they are compared with the results obtained from the first order approach to P MD based on Eq. (13).…”

“…The values of the observed[22] oscillator strengths (×10 8 ) for Eu 3+ in various hosts compared with those obtained from the first-order magnetic dipole contributions…”
