Manchester NMR Methodology Group

Summary:
2DJ spectroscopy separates chemical shift and scalar coupling information into orthogonal frequency dimensions. When combined with pure shift NMR, which suppresses the effect of J-coupling in the directly detected dimension (t₂), pure absorption lineshapes are retained and shearing of the data set is also avoided. The method require long experiment times (it is a pseudo 3D experiment), but retains all chemical shift and J-coupling information with enhanced resolution.
