52 In the absence of retinol, LFP of some carotenoids gives rise to a direct
formation of a small yield of carotenoid radical cation (CAR∑+) via
photoionization. However, this does not interfere with the observed
kinetics since it is easy to distinguish between the instantaneous
formation of CAR∑+ via photoionization and the CAR∑+ formed via
the reaction of retinol radical cation with carotenoid (see Fig. 10B).

25 Oxygen has little influence on the decay of the retinol radical cation
(see Fig. S4†).
26 The lmax value of retinol∑- in aqueous 2.5% TX-100 is 375 nm24a
.
27 In N2O-saturated aqueous 2% TX-100 solutions, the hydroxyl radicals
formed from the reaction of solvated electrons with N2O will be
scavenged by TX-100 via addition or hydrogen-abstraction reactions.28
These reactions will afford carbon-centered radicals, which are known
to be unreactive toward conjugated polyenes such as b-carotene
(Scheme S1†)29.

32 Actually, ketyl radicals have a very small contribution, as indicated
from their weak absorbance (Fig. S7 and S8†), to the transient spectra
observed between 360–420 nm in Fig. 2.
58 LFP of retinol in pyridine as a solvent was reported.9 The transient
spectra showed only an absorption band between 360–430 nm. The
transient at 580 nm was not observed, possibly, due to its fast quenching
by the high pyridine concentration used (~12 M)9.

excluded since this reaction is highly endothermic34.

39 The higher rate constant in acetone can be attributed to the solvent
effect and this was confirmed by the determination of the rate constant
for the reaction of transient A with bromide ions in acetone (kBr = 6.17
1.23 ¥ 1010 M-1s-1, see Fig. S16†).
40 The retinyl cation and transient A show different reactivities toward
tetra-n-butylammonium chloride (0.12 M) in methanol (Fig. S17†). The
low reactivities of these transients towards chloride ions in methanol
can be attributed to hydrogen bonding between methanol and chloride
ions. A similar trend was observed for the reaction of the retinyl cation
with chloride ions in acetonitrile and acetonitrile containing 1.0 M
water (kCl = 2.6 and 0.033 ¥ 109 M-1s-1, respectively)13 and for the
reactions of styrene radical cation derivatives with different halide ions
in acetonitrile and water : acetonitrile (4 : 1)36.
