Abstract
We report ¹³C NMR spectra of a quasi-one-dimensional quarter-filled organic material (TMTTF)₂AsF₆, which undergoes charge ordering ( $T_{{\rm CO}} = 102$ K) and spin-Peierls phase transitions ( $T_{{\rm SP}} = 14$ K). We found that the doubly split NMR lines originating from charge ordering again merge into one line at $T_{{\rm SP}}$ . This shows redistribution of charge densities or suppression of charge ordering across the spin-Peierls transition.
