    • In our previous study, a correlation between proton affinities (PAs) and angles of intramolecular hydrogen bonds in bifunctional organic compounds was examined. As the angle increases, PA values grow large. A protonated 2,4-pentadione has the angle 141.9°, which corresponds to a small PA value, 207.8 kcal/mol. A protonated 2,5-hexanedione has the angle 160.4°, which corresponds to a large PA value, 213.2 kcal/mol. Yamabe, S.; Hirao, K.; Wasada, H. J. Phys. Chem. 1992, 96, 10261.

    • 2O species, the following geometry has been obtained. equation presented The above structure is by 0.2 kcal/mol more stable than that in Figure 2. The energy difference is very small, which indicates that inter- and intramolecular hydrogen bonds are formed and cleaved instantaneously under the thermal condition.

    • Participations of water trimer (n = 3) and tetramer (n = 4) were tested by means of PM3 calculations. The n = 3 precursor geometry of PM3 was found to be similar to that of B3-LYP(SCRF)/6-31G* in Figure 4. The PM3 calculation is, at least, applicable to precursor geometries. The n = 4 geometry involves four hydrogen bonds, and their linearities become worse than those in n = 3. Thus, the n = 4 geometry is unfavorable, and the water tetramer would not cause the mutarotation. equation presented
