experimental σ iso and δ iso data of Murakami et al. follow an approximate linear relationship, close inspection of these data (reproduced in the Supporting Information (Fig. ) shows that a single linear relationship is not able to accurately describe the correlations between σ iso and δ iso simultaneously for both bridging and terminal fluorine atoms, with each subset of atoms showing systematic deviations from the linear model obtained from fitting to all the fluorine atoms. Murakami et al. were also unable to obtain a satisfactory quantitative relationship between their calculated and experimental for the magnetic which prevents the quantitative prediction of spinning sidebands.
