Abstract
The new harmonic inversion noise reduction method was applied to (15)N natural-abundance NMR spectroscopy and N(5)SbF(6). This method is superior to conventional Fourier transform methods for processing FIDs and permits the detection of natural abundance (15)N NMR signals with significantly reduced numbers of scans and improved sensitivity. In addition to the confirmation of the previously reported chemical shifts for N(5)(+), the one bond coupling between N(beta) and N(gamma) could be observed for the first time. Its absolute value is compared to known coupling constants of other covalent azides and the free azide ion.Keywords
