Inhomogeneous B0 and B1 fields are inevitable under some circumstances, and are obstacles for high-resolution magnetic resonance spectroscopy (MRS). Here we show that the effects of inhomogeneous B0 and B1 fields can be almost completely removed via detection of intermolecular double-quantum coherences, while retaining the high-resolution information of chemical shifts, multiplet patterns, J coupling constants and relative peak areas.
