title: A general survey of the proton spin-lattice relaxation-times of some oligo- and poly-saccharide derivatives.
abstract: A Fourier-transform method has been used to measure the spin-lattice relaxation-times (T1 values) of the anomeric protons of a selection of oligo- and poly-saccharide derivatives. Although systematic variations are found for the substances of lower molecular weight, these variations are essentially non-existent at higher molecular weights. Data for the disaccharides cellobiose, maltose, lactose, gentiobiose, and melibiose demonstrate that proton T1-values may provide a powerful method for evaluating conformations of oligosaccharides.
