    • One of the reviewers indicated the different view on the origin of the broad transient spectra as being due to the complexes being adsorbed at different sites. Nonexponential decays of the transient absorption can be explained by the same assumption according to the reviewer. Our interpretation stands of the previous studies of the band shapes of the CT complexes in various media. We share the same view for the nonexponential decays; however, we do not have enough evidence for the transient spectral shift depending on the adsorption sites.

    • One of the reviewers suggested that the increase in the decay rate of excited CT complexes upon addition of water can be explained by the change in polarity inside the zeolite. We assume that the CT complexes adsorbed on zeolites behave differently from those in solution. Hydration of the complexes is unlikely because they crystallize when deprived of the adsorption sites in the zeolites by the water molecules in quantities to fill the entire pore volume. We assume that the CT complexes liberated from the interaction with the immediate surface of the zeolite reside in the free volume within the cage in the presence of a relatively small amount of water and thus relatively free from the influence of water as well as from that of the zeolite surface. Besides, the polarity may not increase dramatically on addition of water, as discussed in section 2 of the Results and Discussion.
