Description
Summary:First principles calculations and solid-state NMR experiments are used to distinguish between possible hydrogen bonding networks in α-d-galactose. In contrast to 13C, the 1H chemical shift parameters show differences which are sufficient to allow the correct network to be identified by comparison with experiments which make use of modern homonuclear decoupling schemes. In addition, clear linear correlations are established between both 1H chemical shift and chemical shift anisotropy, and hydrogen bond length. © 2010 Elsevier B.V. All rights reserved.
