25_05/1986The Cover picture clearly demonstrates that good quality high resolution 15N-NMR spectra (0.1 Hz resolution) can now be measured even at natural isotope abundance (0.37%). Top: Proton-coupled INEPT 15N-NMR spectrum of 2-acetylpyridine (nonselective polarization transfer of the protons). Bottom: The same spectrum with selective decoupling of the methyl protons. In view of the ubiquitous occurrence of nitrogen and its indispensability for all living processes it can be safely predicted that 15N-NMR spectroscopy will rapidly increase in importance. Further details are reported by W. von Philipsborn et al. in a review on p. 383.
