Nuclear magnetic resonance (NMR) results are presented for lithium in several powder samples with a composition near Al6Li3Cu which suggests a strong relationship between the cubic R phase and the icosahedral phase. All NMR spectra show a broad component which arises from a site in R-phase samples as well as what appears to be a similar site in the icosahedral phase. The pure R phase and samples with an appreciable amount of R-phase materials exhibit a second very narrow peak attributable to Li atom s undergoing rapid motion at a different and perhaps interstitial site.
