Ring currents have played a crucial role in modern chemistry, but they have been analyzzd and discussed almost entirely in terms of their effect upon proton nmr chemical shifts. 2,3 The applica,ion of carbon magnetic resonance spectroscopy to this area has received relatively little attention.
## Abstract Carbonβ13 chemical shifts of the cyclopropyl carbons of eleven 4βsubstituted cyclopropylbenzenes have been measured under conditions effectively corresponding to infinite dilution in DCCI~3~. The substituentβinduced chemical shifts (SCS) of __both__ the Ξ± and Ξ² carbons of the cyclopropa
