^13C nuclear magnetic resonance (NMR) investigations were carried out for a one-dimensional organic conductor, (TMTTF)_2PF_6, to determine the charge dynamics and configuration in the proximity of the spin-Peierls phase-transition temperature, T_<sP>. Although no obvious NMR line splitting associated with the charge-ordering transitions in the intermediate paramagnetic states was observed, the charge separation amplitude was estimated to be ρ_<co>〜0.14 using the ^13C NMR spin-lattice relaxation rates for the distinct lines. The abrupt decrease in the NMR linewidth below 25K and the small anisotropy of the NMR linewidth in the spin-Peierls phase indicate the possible redistribution of the charge separation in the proximity of T_<sP>. The low-temperature electronic states of (TMTTF)_2PF_6 are discussed from a microscopic point of view.
