Title:H-bonding networks in sugar alcohols: identifying glucophores?
Author(s):Alonso, E. R.

Subject(s):Chirped pulse
Abstract:The conformational behaviour of sorbitol and dulcitol has been investigated for the first time using a combination of chirped pulse Fourier transform microwave spectroscopy (CP-FTMW) coupled with a laser ablation (LA) source. The observed conformers have been found to be overstabilised by cooperative networks of intramolecular hydrogen bonds between vicinal hydroxyl groups stretching throughout the whole molecule. A common structural signature - involving hydroxyl groups in the H-bond - has been characterized and ascribed to the glucophore's AH and B sites in accordance with Shallenberger’s old proposal.\footnote{R.~S.~Shallenberger, T.~E.~Acree, \textit{Nature,} \textbf{1967}, \textit{216}, 480-482}$^{,}$\footnote{R.~S.~Shallenberger, T.~E.~Acree, C.~Y.~Lee, \textit{Nature,} \textbf{1969}, \textit{221}, 555-556}
