Abstract

Shift work: The new NMR technique, instant homonuclear decoupling, which is achieved by slice-selective homo-decoupling during acquisition, yields pure-shift NMR spectra (see picture) which can be recorded like regular 1D spectra. No special data processing is necessary and this approach can also be easily adapted for the direct dimension of two- and multidimensional spectra, giving improved resolution.
