H/lH isotope effects on the "F chemical shifts of 4-substituted bicyclo[2.2.2]octl-y1 and bicyclo[2.2.l]hept-l-y1 fluoride are significantly shielding and deshielding, respectively. This result is consistent with deuterium being viewed as an electronegative substituent relative to hydrogen when atta
Box 147, Liverpool L69 3BX, UK The 'H chemical shifts and substituent chemical shifts (SCS) were recorded for several monosubstituted norbornanes and bornanes. The observed substituent effects are generally similar for the two ring systems, but differ considerably from those observed for the cycloh
