Abstract Absorption spectra of seven biflavonyls were investigated. They were compared with those of the structurally related hydroxy‐flavones and haloflavones. Such spectrographical data, as well as the considerations of the electron density distribution and of the steric hindrance led to the establishment of the configurations of the biflavonyls in question.
