The =C chemical shifts of a series of isoflavones having hydroxy, acetoxy, methoxy and methylenedioxy substituents are compared. Some general relationships between substitution patterns and chemical shifts, useful for the identitication of naturally occurring isoflavones, are outlined.

## 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
