✦ Synopsis
Ab initio optimizations at the HF/6-31G level and single-point calculations at the MP2/6-31G**//6-31G level were performed on ethane-1,1-diol and ethane-1,1,2-triol. Their conformational properties are discussed in terms of the anomeric effect, gauche effect and internal O-H interactions. The results showed a parallel behaviour with ethane-1,2-diol. The solvent effect was taken into account using the SCRF theory with a general cavity shape which is defined by the molecular surface.
