Abstract:
Improved pulsed-field gradient echo methods are presented and discussed for the direct selective excitation of the (13)C-satellite lines in overcrowded (1)H NMR spectra of small molecules. Sensitivity enhancements in (13)C spin-state selection can be achieved by combining multiple-proton-frequency excitation and Hadamard phase encoding. Several satellite-selective (SATSEL) NMR experiments are proposed and exemplified by measuring the sign and the magnitude of small, long-range proton-carbon coupling constants for (1)H resonances showing several levels of signal overlapping.

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
