Nuclear Magnetic Resonance studies of DNP-ready trehalose obtained by solid state mechanochemical amorphization

Autor: Filibian, Marta, Elisei, Elena, Serra, Sonia Colombo, Rosso, Alberto, Tedoldi, Fabio, Cesàro, Attilio, Carretta, Pietro

$^1$H nuclear spin-lattice relaxation and Dynamic Nuclear Polarization (DNP) have been studied in amorphous samples of trehalose sugar doped with TEMPO radicals by means of mechanical milling, in the 1.6 K $\div$ 4.2 K temperature range. The radical

This paper deals with the comparative use of the chemical shift surfaces to simulate experimental 13C CPMAS data on amorphous solid state disaccharides, paying particular attention to -1-1 linkage of trehalose, to -1,4 linkage between pyranose

Publikováno v: Journal of Chemical Physics 126 (07/01/2007) 014511

The aim of this article is to assess the ability of chemical shift surfaces to provide structural information on conformational distributions of disaccharides in glassy solid state. The validity of the general method leading to a simulation of inhomo
