A selective one-dimensional HSQC experiment was used to obtain heteronuclear long-range coupling constants for native and chemically modiÐed cyclodextrins (3,6-anhydro-b-cyclodextrin) and a non-covalent complex of a-cyclodextrin with p-nitrophenol. Selective excitation was performed on C-4 in the a-
## Abstract A 3D ^1^H–^13^C–^1^H refocused INEPT transfer experiment is proposed in which the initial coherence transfer of ^1^H longitudinal to ^13^C transverse magnetization is tuned to the long‐range ^1^H, ^13^C couplings while the reverse INEPT component transfers the magnetization to the direc
