    • Quenching reaction by oxygen is underisable for the yield of the radicals. Moreover, it causes additional contribution to the TG signals due to the diffusion of unknown species (see ref 13).

    • See the tendency of the solute effect, for example: Roberts, C. B.; Brennecke, J. F.; Chateauneuf, J. E. AIChE J. 1995, 41, 1306. We consider that the solute effect is not too serious to change our following discussions, unless the density in our measurement reaches the vicinity of the critical point.

    • To check the reliability of this method, we have evaluated q values from a nitrobenzene solution which generates only the thermal grating after photoexcitation. We have found no significant difference of q values estimated by the nitrobenzene solution from those by the sample solution.

    • The signals do not often reach baseline after first decay completely in the time scale of figures. This may be due to the small contribution of Δk. Therefore, we had a temporal term Δk(t) to the fitting functions for the analysis. This additional term is fairly smaller than other controbutions of Δn.

    • The radius of diphenylmethanol is larger than 0.04 Å than that of BP using the estimation of ref 9. Even if the radius of BPK is larger than that of BP, it will not exceed that of diphenylmethanol at least. The radius of APK is not either larger than that of α-methylbenzyl alcohol.

    • 2 are primarily affected by the solvent viscosity, not by the solutes. In this analysis, we used the viscosity values which were taken from the equation suggested by Feenqhour et al. (J. Phys. Chem. Ref. Data 1998, 27, 31).
