摘要：

Complexation of Na+-ion with polyethers and polyamides is studied by using 23Na NMR spectroscopy. The variation of the linewidth and the position of the 23Na NMR signal give evidence for the interaction of oxygen atoms of poly(ethylene oxide) in acetonitrile and those of siloxanes in T.H.F. with the solvated ion. In addition chemical shift data are given for perturbation of the Na+ solvation shell by interaction of the ion with substituted amides and polyamides in T.H.F. © 1979.
