Abstract

The first NMR data of alkali-metal ion nuclei ( ⁷Li) in magnetic molecular rings was discussed. The Li nuclear magnetic resonance (NMR) spectra and nuclear pin-lattice relaxation rate (NSLR) measurements as a function of temperature from 1.5 to 50 K with applied field H = 1.5T were reported. It was found that the unsolved problem in magnetic rings was the determination of the temperature T spin dynamics and its effects on the nuclear relaxation. It was observed that the maxima in both Li and H NSLR pointed towards a slow electronic spin dynamics at temperatures of the order of J/k _b.
