Abstract
We obtain the logarithmic corrections to the dynamic response function and nuclear magnetic resonance (NMR) T-1- and T-2G-rates in the spin-1/2 antife rromagnetic Heisenberg chain using the perturbative renormalization group f or the leading irrelevant operator. The result is compared with NMR experim ents on Sr2CuO3.
