Molecular mechanics calculations using the Boyd computer program have been performed to investigate the structure and energy of various conformations of 1,3-cycloheptadiene (1) and 1,4-cycloheptadiene (11). Molecule I has two stable symmetric conformations, IC and LC, and one energetic transition state conformation. The only stable conformation of compound 11 is the asymmetric (ILC) which undergoes energetic and symmetric conformations, ILC and IHCG, to reach the time-averaged C27 symmetry. The features of the potential energy diagram and the ways in which the various conformations can be converted into each other are discussed, and some predictions are made regarding the experimental investigation of the conformations of these two molecules.
