The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d

13C NMR spectra of free bleomycin A, at pH 4 and 6.7 and of its zinc complex at pH 6.7 were completely assigned by making use of two-dimensional 'H-"C correlated spectroscopy. Differences in resonance positions between the spectra of the free bleomycin at pH 4 and 6.7 are observed for the /?-hydroxy
## Abstract The ^1^H (400 MHz) and carbon ^13^C (100 MHz) NMR peak assignments of two oxymorphone alkaloids including the free base and the hydrochloride (HCl) salt and four oxycodone alkaloids including the free base, the HCl salt, the __N__βoxide and the methyl iodide quaternary salt were assigne
