✦ Synopsis

The structure of noncrystalline sucrose in the amorphous, solid state and in aqueous solution was investigated. Differences of structure of amorphous solid samples, the quenched-melt, and freeze-dried sucrose, are revealed by differential thermal analysis (d.t.a.) and from the Fourier-transform infrared (F-t.-i.r.) spectra. Factor analysis of the F.t.4.r. spectra of aqueous solutions of sucrose shows the existence of at least two forms of the sucrose molecule. Analysis of 13C-n.m.r. spectra of amorphous and crystalline sucrose reveals a sensitivity of the fructosyl moiety to the morphology of the sample. M ~lATHLOUTH1.
