## Abstract ^13^C chemical shifts of more than fifty bicyclo[3.2.1]octane and bicyclo[2.2.1]heptane derivatives (hydrocarbons, alcohols, ketones and esters) have been determined. The usefulness of ethyl derivatives for the assignment of close ^13^C chemical shifts in bicyclic methyl derivatives is
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
