Low-frequency spin dynamics in the S=1/2 antiferromagnetic spin-chain compound α-VO(PO3)2 has been studied by means of 31P NMR. The nuclear spin-lattice relaxation rate 1/T1 at the P site exhibits H-1/2 dependence on the applied magnetic field (H) at temperatures (T) well above the intrachain coupling strength J/kB = 3.50 K indicating one-dimensional diffusive spin dynamics. The diffusive contribution to 1/T1 decreases on cooling as electronic spins acquire short-range antiferromagnetic correlations within the chain, and vanishes almost entirely around T ≈J/kB. This is accompanied by an apparent increase of the spin-diffusion constant from the value expected in the classical limit. On the other hand, the field-independent part of 1/T1 increases with decreasing temperature, which may be a precursor for the true long-range antiferromagnetic ordering found below TN = 1.93 ±0.01 K.
