    • Much lower estimates, namely, 1.6-1.7 eu have been recently reported for the entropy associated with torsional motions about single bonds in straight-chain alkanes (see: M. Mammen, E. I. Shakhnovich, G. M. Whitesides, J. Org. Chem. 1998, 63, 3168-3175). However, the reliability of the above estimates has been severely criticized (see: G. Ercolani, J. Org. Chem. 1999, 64, 3350-3353).

    • A statistical correction is needed by the equilibrium EMs. The statistically corrected values plotted in Figure 6 were calculated as EM X σ, where σ is the symmetry number of the oligomeric ring. It is x for the cyclic oligomers of Equation (14) and Equation (15), and 2x for the polylactones of Equation (13).
