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.
