The decoupled proton NMR spectroscopy can effectively simplify the spectra and improve the spectral resolution and sensitivity. In this abstract, two new pulse sequences based on homonuclear and heteronulcear intermolecular single-quantum coherences (iSQCs) were presented for high-resolution decoupled spectra in inhomogeneous fields. The experimental results indicate that the sequences are useful for obtaining high-resolution decoupled spectra in modest to severe inhomogeneous fields.
