dc.description.abstract	Polycyclic compounds 1a-c were synthesized to study the diatropic effects of a flanking phenyl ring on nearby CH and CF bonds. F-19 NMR spectra of 1b and 1c were strongly deshielded compared with those of the ring-opened compounds 3b, 7b, and 7c. DMol3 calculations on 1a-c provided quantitative bond lengths and torsional angles to support the conclusion that the downfield shifts in the F-19 NMR spectra are mainly due to steric interactions between the CF bonds and the pi clouds of the phenyl ring(s).	en_US
