✦ Synopsis

In solids containing two nuclear spin species I and S, the magnetic dipolar coupling causing broadening of the S NMR line is partially averaged due to I spin flip-flop motion due to I-I coupling. This paper shows that the effects we observed previously in AgF (Abragam and Winter) are also present in 13C-* H systems in organic solids.

## Abstract In crystalline polyoxymethylene, a system with tightly coupled protons, it is shown experimentally that the averaging of the dipolar local field of protons by multipulse proton homonuclear decoupling leads to a decrease in the spin–spin contribution to the ^13^C rotating frame relaxatio
