- •
Stable carbon isotope ratios of Fe3+/carboxylate mixture exposed to artificial sunlight were measured to gain kinetic isotope effects (KIEs).
- •
Obtained KIEs were used to identify the vailed C
C bond cleaving channel of oxalate.- •
Observed KIEs for the oxalate, malonate, and succinate mixtures were 5.9‰, 11.5‰, and 8.4‰, respectively.
- •
Comparison of the observed KIEs with the proposed photolysis mechanism successfully identified the sequential dissociation of C
C and FeO bonds as the CC bond cleaving channel.
