Highly unsaturated conjugated fatty acids (carotenoic acids) with 5–15 conjugated double bonds were irradiated by flash pulses in the presence of the sensitizer riboflavin. The resulting triplet and radical cation transients were analyzed and the underlying energy and electrontransferreactions determined experimentally and by calculation. The two key antioxidant reactions of carotenoids summarize in ar
