DIPSHIFT experiments

The estimated correlation times for the loop domains of the order of 10 4 s are obtained for the suppressed peaks in the [l-13C]amino-acid-labelled bR, including Gly, Ala, and Leu residues as shown in Figure 24C. The loop dynamics can be also examined by measurements of the 13C-1H dipolar couplings by DIPSHIFT experiment in which fluctuations of the Co,-Cp vector result in additional motional averaging as order parameters, in addition to the rotation of Ala methyl groups which scales the dipolar... 

The presence of anisotropic interactions in solids leads to a greater variety of 2D sequences. One of the simplest is the isotropic/anisotropic correlation, where high resolution is achieved in one dimension while preserving anisotropic information in the second dimension. The dipshift and J-resolved experiments correlate isotropic chemical shift with dipolar and J-coupling information respectively. In these sequences the... 

Conformational motions have been studied." Other line shape experiments include 13c 481,482 P in freeze-dried liposomes,DNA," " cytochrome" and spectra of lipids. The complex dynamics in lipid bilayers was studied by H-2D exchange." Dynamic decoupling found its application" as well as multipulse experiments." SLF experiments like LG-CP," DIPSHIFT" " and determine the amplitudes of fast... 

The molecular dynamics within the crystallites of poly(s-caprolactone), PCL, crystallized from the melt were studied by means of high-field C and H NMR spectroscopy, including C DIPSHIFT and CODEX MAS experiments. Schaeler et al. determined the different molecular regimes within the polymer.
