## It is shown how an CLDOR technique based upon spin echoes and rapid stepping of the magnetic field mrty be cmployed to measure rotariowl correlation times, TR for very slow motions. Experiments on PD-Tempone in 85% &~erol/ D20 at low rempcmtures led to TR KIIUCS of lOA to 10e5 s obtained with a
The effects of nonzero radio-frequency pulse widths on the echo signals in solids with molecular motions have been investigated. It has been shown that in the slow-motion region a time position and an amplitude of the echo signal depend not only on the width of the pulse, but also on the shape of po
