In spite of the importance of localized two-dimensional
correlated spectroscopy, two aspects restrain its wider
applications, namely long acquisition time and poor
performances under inhomogeneous magnetic fields. Here,
a scheme addressed as asymmetrical gradient based
single-scan spatiotemporal localized correlated
spectroscopy (AGE-SEL-COSY) is proposed for ultrafast
high-resolution recording of 2D correlated spectra under
inhomogeneous magnetic fields. Experiments have been
carried out on chemical solution and biological tissue
to prove the robustness of AGE-SEL-COSY against
inhomogeneity. It offers important perspectives for fast
in vivo analyses of metabolites and living inhomogeneous
organisms.
