Abstract NMR studies of the Diels-Alder adduct of phencyclone with norbornadiene have provided evidence for hindered rotation of the two unsubstituted bridgehead phenyl groups at ambient temperatures. In d6-DMSO solution, all 14 of the unique proton signals of this molecule are resolved at 200.1 MHz. 1H chemical shift assignments have been made using the COSY two-dimensional homonuclear shift correlation experiment.
