Table 3. Decay Constants [s^–1] for the Luminescence Lifetime of Europium Complexes in H₂O and D₂O Reported Here, as Well as the Calculated q Values According to the Modified Horrocks Equation³⁹.

	Eu(3)	Eu(4a)	Eu(4b)	Eu(5a)	Eu(5b)
k(D₂O)	0.55	0.51	0.59	0.52	ND^a
k(H₂O)	2.14	1.31	1.77	1.76	ND^a
q	1.4	0.5	1	1.1	ND^a

ND = not determined. Because of the decreased solubility of Eu(5b) compared to the other europium complexes described here, we were not able to generate a solution with high enough complex concentration required for this measurement.
