Correction to: Nature Communications https://doi.org/10.1038/s41467-019-09392-7, published online 4 April 2019.

The original version of this Article contained an error in the eighteenth sentence of the third paragraph of the ‘Determination of Hab and kET data for the Mo2 dimers’ section of the Results, which incorrectly read ‘For 1a+ with 2Hab » kBT, it is inappropriate to calculate the rate constant using Hab for the PCET reaction in the nonadiabatic regime.’ The correct version states ‘2Hab >> kBT ’ in place of ‘2Hab » kBT’.

Also, the third sentence of the Discussion originally incorrectly read ‘The linear relationship of ln(kET) vs. rab gives β = 1.25 (Supplementary Fig. 9).’ The correct version states ‘Rab’ instead of ‘rab’.

This has been corrected in both the PDF and HTML versions of the Article.
