✦ Synopsis

H and '3C chemical shifts, obtained by two-dimensional homonuclear and heteronuclear shift correlation, are reported for 8,8-diethyl-N,N-dimethyl-2-aza-8-germaspiro [4,5]decane-2 -propanamine dihydrochloride (spirogermanium). The chemical shift variations as a function of pH and the coupling constants of the azacyclopentane moiety of the molecule are analysed, and a conformation is proposed for the molecule. ' I pm f 60 50 40 30 20 10

on the physico-chemistry or on the conformational structure of spirogermanium have appeared in the literature, and 1D and 2D NMR spectroscopy may lead to an improved understanding of the molecular conformation.
