H-1- and C-13-NMR spectral data are presented for six p-terphenylquino
ne derivatives 3-8 (and for two monosubstituted quinones 1 and 2, used
as model compounds) and for 9,10-phenanthraquinone (9) and retenequin
one (10). The chemical shifts were confirmed through correlation spect
roscopy and NOE measurements.
