## Abstract Herein are presented the ^1^H and ^13^C NMR data for seven monohydroxyflavones (3‐, 5‐, 6‐, 7‐, 2′‐, 3′‐, and 4′‐hydroxyflavone), five dihydroxyflavones (3,2′‐, 3,3′‐, 3,4′‐, 3,6‐, 2′,3′‐dihydroxyflavone), a trihydroxyflavone (apigenin; 5,7,4′‐trihydroxyflavone), a tetrahydroxyflavone (

The chemical shifts of methyl cation and anion have been calculated. The tensor components about the out-of-plane p orbitals were essentially the same, but the components about the in-plane axes differed by over 700 ppm. The experimental chemical shifts of benzene and the aromatic ions fall on the l
