title: PMR and 13C-NMR spectroscopy of tropane and N-substituted nortropane spirohydantoins.
abstract: The preferred conformations of a pharmacologically interesting series of N-substituted nortropane spirohydantoins were determined from PMR and 13C-NMR data to permit a structure-activity relationship study.
