The infrared spectra of nine N-substituted 3-nortropanones were measured and their carbonyl frequency in 3-position was compared with that of other ketones located in a different position in tropane skeleton. Infrared spectra of several N-substituted 3-nortropanols were measured, especially in C-O stretching region. A regular difference between 3α- and 3β-ols was observed. Some of the N-substituted 3-nortropanones were reduced with sodium borohydride and the structures of resulting bases were presumed from their infrared spectra.
