SIMPLE1H n.m.r. measurements of isotope-shifted resonance for hydroxy groups in sucrose show that hydrogen bonding in solution is different from that observed in the solid state viz. there are two inter-residue hydrogen bonds in competition for one acceptor group (i.e. OH1′⋯ O2 vs.OH3′⋯ O2) and an intramolecular hydrogen-bond network that is nucleated by the inter-residue hydrogen bonds.
