text: It has been observed that in cyclopentanes, γ-butyrolactones (Ollis JCS-PT1 1975, 1480) and tetrahydrofurans the diastereotopic chemical shift effect of a ring CH 2 group is consistently larger when flanking substituents X and Y are cis to each other (when the anisotropic effects of the C-X or C-Y bonds are additive) compared to when they are trans (both protons see the effect).
