23. Yet another mechanism is reductive quenching of the dye by the redox mediator, followed by thermal electron transfer from the dye to the semiconductor. For an example, see: Thompson, D.W.; Kelly, C.A.; Farzad, F.; Meyer, G. J. Langmuir 1999, 15, 650-653.

45. Previous Stark studies of small organic dyes have shown that J-type aggregate formation can induce small changes in |δμ|. Typically, the values increase (see, for example: Gottfried, D.S.; Boxer, S.G. J. Lumin. 1992, 51, 39-50. Beekman, L.M.P.; Steffen, M.; van Stokkum, I.; Olsen, J.D.; Hunter, C.N.; Boxer, S.G.; van Grondelle, R. J. Phys. Chem. B 1997, 101, 7284-7292. Stanley, R.J.; Jang, H.J. Phys. Chem. A 1999, 103, 8976-8984). These studies also report, however, significant increases in δα, which are not observed here.

48. We are aware, however, of preliminary work by B.S. Brunschwig, A.R. Parise, and N. Sutin on the application of Stark absorption spectroscopy to interfacial electron-transfer reactions (Proceedings of the 24th DOE Solar Photochemistry Research Conference, June, 2001, p 87).
