The proton NMR spectra of a series of tetraaryl-3,7-diazabicyclo[3.3.l]nonanes, 5 -12, have been assigned with the aid of nuclear Overhauser difference spectroscopy. The NOE's together with spin lattice relaxation times have been used to show that these molecules adopt the chair-boat conformation wi
The proton NMR spectra of the isomeric 3Λ-and 3Λ-aminotropanes were recorded in aqueous solution over the pH range 2-14 and the resonances of both diamines were completely assigned. The pH dependence of the chemical shifts of the protons Λto the amino groups was used to determine which of the amino
