Transmission spectra of metal-free monophthalocyanine, bis-phthalocyanine of Eu and Eu di-tris-phthalocyanine organic semiconductors were have been obtained and analyzed. Comparison of spectral data from different clam-shell complexes revealed that magnetic ff interaction of Eu atoms increase the energy of vibronic states which is clearly indicated by the spectral shift of absorption lines position. A new set of absorption lines in the 2360 \textdiv 2341 cm1 range was observed. It was suggested that these lines correspond to vibrations of orto-bis(oximetil)phenol group. It was found that vibronic modes of the phtalocyanine-ring reveal several absorption lines with spectral coordinates 526 cm1, 502 cm1, 484 cm1, 467 cm1 in the far infrared region.", }
