A study has been made of the interaction between the thallous and gramicidin dimers incorporated into micelles by using /sup 205/Tl NMR spectroscopy. The chemical shift data obtained are interpreted in terms of a model in which the dimer has only one tight binding site. The binding constant for this site was determined to be 900 M/sup -1/ at 30omicronC. The thallous ion also appears to be partially solvated in the channel.
