Abstract
An experiment is presented that enables the measurement of small chemical shift anisotropy tensors under fast magic-angle spinning (MAS). The two-dimensional spectra obtained give a fast MAS sideband pattern in the directly observed dimension with the spinning sideband intensities equivalent to the chemical shift anisotropy scaled by a factor of N, or equivalently the sample spinning frequency scaled by 1/N, in the indirectly observed dimension. The scaling factor may be arbitrarily varied by changing the number and timings of the rotor synchronized pi-pulses used. Desirable features of the experiment include a fixed length pulse sequence and efficient sampling of the indirectly observed dimension. In addition, neither quadrature detection in the indirect dimension nor storage periods are required, consequently no signal intensity is discarded by the pulse sequence. The experiment is demonstrated using (31)P NMR of sodium phosphate and (13)C NMR of fumaric acid monoethyl ester for which a scaling factor of N=10.2 was employed.

Abstract
An experiment which separates 2H spinning sideband patterns according to the 2H double-quantum chemical shift in a manner suitable for motional studies is proposed. The technique is successfully applied to 4,4'-azoxydianisole at 323 K to separately analyze the motion of the aromatic and methyl deuterons. Comments are made on the formation of a nematic mesophase in this material at 390 K in the light of the results of this NMR study. Copyright 1997 Academic Press. Copyright 1997Academic Press

Abstract
The dynamics of the glycerol headgroup of dioleoylphosphatidylglycerol (DOPG) in hydrated bilayers were studied by 2H and 31P NMR spectroscopy, and the effects of binding a peripheral protein, cytochrome c, were evaluated. The fast headgroup segmental motions (tau c, 10(-10)-(-13) s) of DOPG in fully hydrated bilayers were not affected upon binding of cytochrome c, as evaluated by the spin-lattice (T1) relaxation of deuterons in the DOPG glycerol headgroup. In contrast, the spin-spin (T2e) relaxation is strongly affected, indicating that slow cooperative bilayer motions (tau c, 10(-3)-10(-6) s) are enhanced upon the interaction with cytochrome c, 2H and 31P NMR spectral lineshape analysis reveal details of the nature of these motions. The importance of these effects are discussed in terms of a possible mechanism for modulating membrane-associated processes.
