20. The kinetic evaluation is given in ret 3b.
21. The details of this measurement as well as the synthesis carried out by Dr. A. M. Braun in our laboratory will be published in a forthcoming full paper.

23. We are grateful to the referees and to Professor C. A. Bunton for suggesting such a possibility. Preliminary experiments using C-isMV2+ as an electron acceptor strongly corroborate this conclusion. Here, in the presence of CTAC micelles, there is practically no quenching of the Ru(bpy>32+ excited state by the viologene. Apparently the octadecyl chain renders this molecule sufficiently hydrophobic to allow for mixed micelle formation with CTAC.
24. The back-reaction is accelerated by increasing the ionic strength. For example, addition of 10”2 M NaCI produces ~30% augmentation of k3.
25. Owing to low frequency noise interference with measurements on relatively long time scales, only an upper limit for the rate constant can be given.
