    • Here, we simply adopt the term "proton transfer" rather than "hydrogen atom transfer" throughout the text, because it is more suitable in describing the solvent polarity coupled dynamics.

    • ESIPT is prohibited for some 6, five-membered ring types of strong intramolecular hydrogen bonding molecules with an nπ* configuration as the lowest singlet manifold. For a recent review, see ref 3a.

    • ESIPT incorporating phenol O-H to a β-carbon atom is not included in this category, see: Lukeman, M.; Wan, P. J. Am. Chem. Soc. 2002, 124, 9458. Also, a recent study on 5-(2-pyridyl) 1-H-pyrazoles in nonpolar solvents reveals an intrinsic ESIPT incorporating an appreciably large energy barrier due to the skeletal reorganization, see:

    • In protic solvent, perturbation via intermolecular hydrogen bonding formation may complicate the ESIPT mechanism and thus is not considered in this study. For a recent study of system I in protic solvent, see: Shynkar, V. V.; Klymchenko, A. S.; Piemont, E.; Demchenko, A. P.; Mely, Y. J. Phys. Chem. A 2004, 108, 8151.
