Integral intensities of the absorption bands of the skeletal vibrations of substituted furocoumarins

  • G. A. Kuznetsova
  • G. Z. Mamatov


The IR spectra of 5- and 8-hydroxyfurocoumarins and their esters, 5,8-disubstituted furocoumarins containing hydroxyl, methoxyl, and alkoxyl groups, and 4′,5′-dihydrofurocoumarins differ with respect to the intensity and number of the bands in the 1630–1500 cm−1 region of the spectrum. The integral intensities of the absorption bands in this frequency region differ markedly in the derivatives mentioned.
