Abstract
Molecular mobility in two similar organic glass formers, namely sorbitol and maltitol, is studied in order to understand their difference in the cross-over between \(\) and \(\) relaxations, far above their respective glass transition temperatures. In this goal, the individual mobility of each carbon atom of the 6 carbon chain present both in sorbitol and maltitol is studied by means of ^13C nuclear magnetic resonance and molecular dynamics simulations. Both techniques imply that the mobility of carbons located at the end of the 6 carbon chain is greater than that of any other carbon of this chain and that the difference in carbon mobility is greater within the sorbitol moiety of maltitol than in sorbitol. The relaxation time obtained by magnetic resonance for carbons at the end of the 6 carbon chain is related to the \(\) relaxation time and the one of carbons in the middle of the chain is in relation with the value of the \(\) relaxation time. This result may suggest that the merging between the \(\) and \(\) relaxation processes in both sugars would be related to the decrease of the differences in mobility between the atoms of 6 carbon chain.
