Slow global motions in biosolids studied by the deuteron stimulated echo NMR experiment

Slow global motions in biosolids studied by the deuteron stimulated echo NMR experiment

Recent 15N R1?-relaxation studies have shown that proteins in the solid state undergo slow, low amplitude global motion in the sub-millisecond time range. This range is at the edge of the time window for R1? experiments and, therefore, the motional parameters obtained by this method are not precise or reliable. In this paper, we present a 2H stimulated echo study of this type of molecular dynamics. The 2H stimulated echo experiments on a static sample allow for direct measurement of the...
