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, 2009 ![]() |
