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.
It has been well established that the 13 C chemical shift of ring carbon atoms normally moves to higher field with decreasing ring size both for carbocyclic 1 and saturated heterocyclic2 compounds. Recent work3 has shown that in compounds where two of the cyclo-
