## Abstract The ^1^H and ^13^C NMR spectra of 3‐azabicyclo[3.3.1]nonanes with various oxygenated substituents at C‐6 were assigned using 1D (DEPT) and 2D (COSY, HSQC, HMBC, NOESY) experiments. Close examination of this NMR data details the effects of substitution and stereochemistry at C‐6 in these
