Analyzing Lanthanide-Induced Shifts in the NMR Spectra of Lanthanide(III) Complexes Derived from 1,4,7,10-Tetrakis(N,N-diethylacetamido)-1,4,7,10-tetraazacyclododecane

Lanthanide-induced shifts (LIS) in the NMR spectra of lanthanide(III) complexes derived from 1,4,7,10-tetrakis(N,N-diethylacetamido)-1,4,7,10-tetraazacyclododecane. Linear least-squares analysis was used to interpret the data. Molecular mechanics combined with LIS algorithms were used to calculate the solution structures of the complexes. Molecular structure parameters are presented.
