RESUMO

In this work the most abundant trehalose conformers for the isolated molecule as well as for the water solvated system are selected. The theoretical tecniques employed are ab initio calculations in the gas phase and in aqueous solution using the PCM model. A conformational map is built for the glycosidic angles (phi and psi) and the search for the most abundant structures is explained. The final structures are validated by the agreement found between experimental and theoretical values for ³J H,C along the glycosidic linkage.
