Spatially encoded ultrafast high-resolution 2D homonuclear correlation spectroscopy in inhomogeneous fields

► Ultrafast high-resolution COSY and TOCSY were obtained in linear inhomogeneous fields. ► Limitation in resolution due to spectral width of indirect domain was alleviated. ► COSY and TOCSY were reconstructed from SECSY and SETOCSY, respectively. ► The experimental results were consistent with theoretical predictions.
