Mhp. Vangenderen et al., OBSERVING INDIVIDUAL GENERATIONS IN POLY(PROPYLENEIMINE) DENDRIMERS WITH NATURAL-ABUNDANCE N-15-NMR SPECTROSCOPY, Recueil des travaux chimiques des Pays-Bas, 113(12), 1994, pp. 573-574
Natural abundance N-15-NMR spectra of poly(propyleneimine) dendrimers
are presented to show the usefulness of the technique in characterizin
g these highly branched and well-defined macromolecules. Inverse-gated
decoupled measurements show the number and intensities of signals tha
t reflect the generations in the dendrimers.
