The time integrals of the two-time auto and nearest-neighbor spin-pair correlationfunctions are calculated for the spin 172 isotropic Hcisenberg magnet with anti-ferromagnetic exchange integral in the paramagnctic region. They are used to estimatethe temperature dependence of the NMR line width of F" in RbMnF.. The obtainedresult is in an excellent agreement with the experimental data uneasured by Hess andHunt. A conjecture is presented for the temperature dependence of the time integrals ofthe two-time spin-pair correlation functions at high temperatures.
