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

Introduction of a fluorine substituent into an aromatic ring of [2.2]paracyclophane causes distinct shielding and deshielding effects at the anti -and syn-protons, respectively, of the adjacent bridge methylene group. A recent contradictory claim in the literature was disproved by 2D H,H-NOESY, long

## Abstract Carbon‐13 NMR spectral data for a series of symmetrical 2,6‐disubstituted adamantanes (O, CH~2~, CH~3~, OH, OCOCH~3~) are presented. The substituent effects on ^13^C chemical shifts are additive, except for carbons 2 and 6 in 2,6‐adamantanedione. The non‐additivity of the substituent

## Abstract Substituent effects on the ^13^C and ^1^H chemical shifts have been studied for derivatives of 3‐benzylidene‐2, 4‐pentanedione. A significant correlation has been found between chemical shifts of the __Z__ carbonyl group (C‐2) and Hammett constants, while no correlation has been found f
