Rye of Yale's Department of Geology and Geophysics we have measured the isotope effect at 1.8 K. We find an increase in the 13C/12C ratio of 0.5% in going from BPO to CO2, where Sagdeev et al. reported a decrease of 30% at 4.2 K.

- Cadogan , J. I. G. , Hey , D. H. and Hibbert , P. G. 1965 . J. Chem. Soc. , : 3939 have proposed induced decomposition mechanisms for BPO which involve radical attack at the para position. A mechanism for the 1,4-hydrogen shift and decarboxylation, which would be required in the present case is not obvious.

- The benzene-grown crystal illustrated in Figure la of Reference 8 is indexed incorrectly. This raises additional questions about the subsequent interpretation in that paper.
- Although Barchuk et al. did not claim this fine a distinction, it is almost surely attainable.
- Barchuk et al. proposed that the transition is polarized along the C–O(peroxy) bond, which makes an angle of 70° with [010]. If this be so, it must be completely different from the transition we have characterized above.
- This description is approximate because the {110} planes make angles of 32.1° rather than 45° with [010].
