## Abstract Carbonβ13 NMR chemical shifts are reported for six angular and one linear dichloropyridoquinolines in CDCl~3~. The chemical shift assignments have been made using model compounds, fully coupled spectra, selective proton decoupling and results from lanthanide shift studies. Chlorine subs
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.
