Abstract
The NMR Tl-203 and Tl-205 spectra of [Tl4Cl]3+ clusters introduced int o pores of sodalite were studied. The well-resolved fine structure of the spectra revealed that a strong indirect exchange interaction of Tl nuclear spins in clusters takes place (J=28.1+/-0.2 kHz), and the int ercluster interaction of Tl spins is found to be negligible. Compariso n with earlier data using the indirect thallium spin-spin interaction in bulk TlCl indicates a sharp increase of the contribution of the mul tiparticle interaction in [Tl4Cl]3+ clusters as a result of conditions of quantum confinement in the structure pores of sodalite.
