Pulse Sequences to Observe NMR Coupled Relaxation in AXn Spin Systems
Abstract
NMR pulse sequences that are modifications of the HSQC experiment are proposed to observe 13C-coupled relaxation in AX, AX2, and AX3 spin systems. 13CH and 13CH2 moieties are discussed as exemplary AX and AX2 spin systems. The pulse sequences may be used to produce 1D or 2D proton NMR spectra.
