    • note
    • Six of the eight solvents yield plots that clearly display two activation regimes and a well-defined transition temperature (cf. Figure 1). Methyl benzoate and dichloropropane, however, yield plots that are nonlinear, but less obviously dual component - at least over the accessible temperature ranges. Nevertheless, for completeness, we have assumed that the observed curved Arrhenius plots are dual-component plots and have reported best fit parameters (Table 1). Clearly, however, the parameters should be regarded as much less certain than those reported for other solvents

    • tr were the same for all solvents.) Krug et al. ( Nature 1976, 267, 566; J. Phys. Chem. 1976, 80, 2235, 2341) have pointed out that apparent enthalpy/entropy correlations can readily arise from a correlated propagation of experimental errors. They argue that free energy vs enthalpy correlations, at an average experimental temperature, offer a means for assessing the chemical validity of enthalpy/ entropy correlations (since experimental errors for the former should be statistically uncorrelated). The data in Table 2 fail this test (r = 0.28), indicating that the correlations are likely spurious.

    • note
    • A reviewer has pointed out that if the Coulombic exlanation is correct, the excited-state folding equilibrium could likely be altered by derivatizing the bipyridyl ligand so as to yield a ligand-localized π - π*state, in place of the charge transfer state, as the lowest-lying excited state.
