| Abstract: | The effect of intrinsic asymmetry on chemical shifts in a more generalized situation than that of diastereotopic groups is illustrated using substituted ethanes in which rotation is slow on the NMR timescale. The effect of different substituents on the magnitude of the asymmetry shifts is demonstrated and is tentatively linked to bond polarisability. |
