A selective one-dimensional HSQC experiment was used to obtain heteronuclear long-range coupling constants for native and chemically modiΓed 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-
Long-range heteronuclear coupling constants, n J XH , have been recognized as an important source of information in the structural elucidation of molecules (1). Accordingly, a large number of methods for their measurement have been proposed to date . Often these methods rely on the characteristic sp
