Improved pulsed-field gradient echomethods are presented and discussed for the direct selective excitation of the 13C-satellite lines in overcrowded 1H NMR spectra of small molecules. Sensitivity enhancements in 13C 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 1H resonances showing several levels of signal overlapping.
