Abstract
Infrared absorption spectra of copper phthalocyanine in KBr pellet and pyridine solution in 400–1625 and 2900–3200 cm−1regions are reported. In the IR spectra of solid sample, presence of weak bands, which are forbidden according to the selection rules of D4h point group, is explained on the basis of distortion in the copper phthalocyanine molecule caused by the crystal packing effects. Observation of a new band at 1511 cm−1 and change in intensity of some other bands in pyridine are interpreted on the basis of coordination of the solvent molecule with the central copper ion.
