Direct Observation of a Transiently Formed Isomer During Iodoform Photolysis in Solution by Time-Resolved X-ray Liquidography (vol 9, pg 647, 2018)

초록

In the published Letter, the quantum yield of excited iodoform was underestimated, which was caused by a simple mistake in the scaling of the experimental scattering curves to the theoretical ones. To resolve this issue, we reanalyzed the data using the new scale factor. Accordingly, the time-dependent concentrations in Figure 4c and the related bimolecular rate constants in Figure 4a have to be modified. The corrected bimolecular rate constants are 6.46 ?0.02 ?109 M-1 s-1 for I + I ? I2 and 2.71 ?0.01 ?109 M-1 s-1 for CHI2 + I ? CHI3. The corrected Figure 4 is presented here. The quantum yield for excitation and the fraction of the excited state that relaxes back to the ground state without undergoing isomerization or fragmentation reaction are 11.3 ?0.1% and 18.5 ?2.9%, respectively, although these were not reported in the published Letter.
