Abstract

We report a study of the ²⁰³Tl and ²⁰⁵Tl Nuclear Magnetic Resonance of the ternary semiconductor TlTaS₃ that shows a chain structure. Our measurements show noticeable intra-chain (Tl-Tl) and inter-chain (Tl-Ta) indirect nuclear spin-spin interactions. These couplings result from the overlap of the Tl and Ta electron wave functions across the intervening S atom, in contrast with the expected 1D-behavior of the compound. The experimental results are in good agreement with the calculated electronic band structure. The role of the 6s² electron pair of Tl in interatomic interactions is discussed.
