| Abstract | The interactions of carotenoids with NO2. were investigated by pulse radiolysis. Optical traces show bleaching of the ground-state absorption off-carotene, zeaxanthin and canthaxanthin at 450 nm, and bixin at 460-510 nm. The transient absorption spectrum shows that the positive absorption attributed to the formation of carotenoid addition radicals cannot be observed in the range of 600-700 nm. It is suggested that carotenoids undergo more readily electron transfer with NO2. to yield the carotenoid radical cations. The rate constants for the reaction of beta-carotene, zeaxanthin, bixin and canthaxanthin with NO2. obtained are 1.6 x 10(8), 2.41 x 10(8), 5.41 x 10(7) and 1.75 x 10(7) mol/(L-1 center dot s(-1)), respectively. |
