Abstract

The ¹³C NMR spectra of the conducting salt (TMTSF)₂(Ni(tds)₂) have been recorded across the metal-metal transition at 272 K. The changes in the NMR spectra are related to the changes in the symmetry of the system and to variations in the Knight shifts. Below the transition there is a decrease in symmetry, in agreement with previously published X-ray data. The NMR data demonstrate that the structural modification associated with the transition extends over a much wider temperature range than suggested by ESR and conductivity measurements. A comparison with the spectra of the Bechgaard salts reveals the sensitivity of the technique to variations in the distribution of conduction electrons.
