✦ Synopsis

A pulsed field gradient version of the sensitivity-enhanced 2D TOCSY experiment is proposed which yields high-quality spectra with improved sensitivity and a minimum of two scans per t1 increment. For rapid acquisition of 1D TOCSY spectra, the 1D DPFGSE-TOCSY experiment was modified to include phase-encoded multiple-selective excitation followed by a simple spectral editing. Combination of these two building blocks is used in a sensitivity-enhanced 2D analog of the 3D TOCSY-TOCSY experiment which provides an efficient tool for resolving severely overlapped signals of oligomers in short experimental time.

A pulsed field gradient version of the sensitivity-enhanced 2D HSQC-TOCSY experiment is proposed for measurement of long-range heteronuclear coupling constants. The coupling constants are obtained by computer-aided analysis of mixed-phase multiplets with and without the heteronuclear splitting. Gene

This paper is devoted to sequences involving a selective inverting pulse bracketed by two identical B,, gradient pulses [pulse field gradient spin echo (PFGSE)]. The merits of a single PFGSE experiment vs. a double PFGSE experiments are discussed. It is shown that the SPFGSE experiment gives results
