Pulse sequences which generate multiple-and zero-quantum coherence and suppress the detection of single-quantum coherence have ben used to greatly reduce the intensity of the water signal in NMR images. In the experiment, image signals having multiplequantum behavior add constructively while single-
The 400βMHz ^1^H NMR analysis of alcoholic beverages using standard pulse programs lacks the necessary sensitivity to detect minor constituents such as methanol, acetaldehyde or ethyl acetate. This study investigates the application of a shaped pulse sequence during the relaxation delay to suppress
## Abstract Alginate is a linear copolymer of 1β4 linked Ξ²βDβmannuronic acid (M) and 1β4 linked Ξ±βLβguluronic acid (G). The physical properties of these polysaccharides such as gel properties and viscosity are largely correlated to the monomer composition (M/G ratio), the sequence of the polymer an
