The original version of this Article contained errors in values of Δrot, krot, ΔG, ΔH, ΔS and –TΔS in the last paragraph of the Results section. An error in the eighth sentence of the last paragraph of the Results incorrectly read ‘442 ps and 2.26 GHz’. The correct version states ‘11.1 ps and 89.9 GHz’. An error in the ninth sentence of the last paragraph incorrectly read ‘ΔG = +4.67  kcal mol–1, ΔH = +1.40 kcal mol–1 and −TΔS = +3.27 kcal mol–1’. The correct version states ‘ΔG = +2.50 kcal mol–1, ΔH = +1.28 kcal mol–1 and −TΔS = +1.22 kcal mol–1’. This has been corrected in the PDF and HTML versions of the Article.

The original version of this Article also contained an error in Fig. 5d, in which incorrect values were given for ΔG, ΔH, ΔS, and the scales of the y-axes in both the main graph and the inset graph were incorrect. The correct version of Fig. 5d is:

which replaces the previous incorrect version:

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

The original version of the Supplementary Information associated with this Article contained an error in Supplementary Table 7, in which incorrect values were given in the third and fourth columns from the left. The correct version of Supplementary Table 7 is:
