The existence of extended homonuclear coupling structures causes signal overlaps in 1D and 2D proton spectra. Numerous techniques have been developed through years to reduce multiplet patterns into singlets. A new approach is proposed here. The combination of a 2D experiment decoupled in the F1 dimension - by the introduction of a homodecoupling element in the evolution time - with spectral aliasing and frequency modulation of pulses leads to the obtention of 1D homodecoupled proton spectra with enhanced spectral resolution and sensitivity.
