The '"0 NMR chemical shift data for 23 9-fluorenones in acetonitrile at 75OC are reported. '"0 NMR data for the kubstituted 9-fluorenones are correlated with '"0 NMR data for 4-substituted acetophenones. Chemical shift data for 1-halogen\*9-fluorenones are deshielded relative to the fisomers, sugges
