The influence of homonuclear coupling contributions in 13 C and 29 Si NMR refocused–decoupled 1D/2D INEPT experiments was graphically visualized by monitoring the computed variations of the theoretical signal intensities as a function of the refocused delay time Δ. The appearance and exploitation of a hitherto unknown characteristic ‘geometrical imprint domain’ closely linked to the spatial environment around the heteroatom under investigation allow a straightforward editing of the spectra. © 1997 John Wiley & Sons, Ltd.
