摘要

The rate constants for decay of the Eu~(3+)(~5D_0)) excited state are reported for aqueous Eu(dipicolinate)_n~(3-2n) complexes with n = 0-3 in H_2O and D_2O at 295 K. These rate constants are used to estimate water coordination numbers,and the results are compared to parallel molecular dynamics calculations, showing good general agreement. Electronic energy exchange between species with differing numbers of coordinated dipicolinate ligands is examined and is found to be most significant for species of opposite charge.
