摘要：
We present C-13 spin-lattice relaxation time and EPR susceptibility measurements on selectively enriched single crystals of (TMTTF)2Br over a wide temperature domain. These are shown to satisfy 1D dynamic scaling for the existence of 1D paramagnons and antiferromagnetic correlations up to room temperature. Applied to bromide salt which undergoes a Mott-Hubbard localization under 100K, our approach confirms the spin-charge separation predicted for the 1D correlated electron gas model and provides a qualitative evaluation of the amplitude of AF fluctuations.
