## Abstract The bimolecular rate constants __k__~q~ for quenching of singlet oxygen (^1^Ξ~g~ state) by 26 different natural and novel synthetic carotenoids were determined at 37 Β°C in a mixture of chloroform and ethanol. The steadyβstate technique used involves the generation of ^1^O~2~ by thermal
The ralc conskmts of quenching of singlet :mtl triplet states by oxygen hnve been measured for nine :~rom:~~ic h.vdroc:Irbons in solution. Singlcl quenching is diffusion controlled and similnr in nil cases but triplet quenching is slo~cr :md the quenching rrltc constant is closely r&ted to the recip
