Abstract

New two‐dimensional ω, and ω~1~, ω~2~ semi‐selective homonuclear and heteronuclear NMR experiments recorded with pulsed field gradients (PFGs) were designed and tested on two peptides. The use of PFGs improves dramatically the performance of the semi‐soft experiments. The complete absence of t~1~ modulations allows the observation of cross peaks which are buried in the noise. The same principle as described here can also be implemented for recording three‐dimensional and four‐dimensional semi‐soft experiments.

## Abstract A pulsed field gradient one‐dimensional NMR selective ROE (rotating frame NOE) experiment was designed and successfully tested. The resulting spectra are of high quality and devoid of artefacts. Hence reliable quantification of very weak ROEs necessary for the three‐dimensional structur

Three new gradient-selected NMR experiments for the analysis of long-range heteronuclear coupling constants are presented. They are demonstrated on a series of compounds including sucrose, strychnine and a complex macrolide, phormidolide, isolated from a marine cyanobacterium. These 1D and 2D hetero
