Figure 6
Torsional distributions from the CSD about the central C—C bond in three simple substructures: (a) butane (CH3—CH2—CH2—CH3), (b) 2-methylbutane [(CH3)2—CH2—CH2—CH3] and (c) 2,3-dimethylbutane [(CH3)2—CH2—CH2—(CH3)2]. Potential energy curves calculated using Chem3D Ultra (CambridgeSoft, 2009BB19) are superimposed on the distributions. (d) The distribution of Car—Car—S—C torsion angles in arylsulfones from the CCDC's Mogul knowledge base (2008 release).
