Absorption spectra of Yb(DPA)(3)(3-) complex (where DPA=dipicolinate)
in aqueous solution are studied and all of their spectral peaks are, a
ssigned based on Double Sphere Coordination Point Charge Field model(D
SCPCF). It is shown that calculated and observed results are agreeable
to each other. Meanwhile the coordination structure of the complex re
ported in aqueous media are also deduced.
