Abstract:
Quantum chemical calculations reproduced quite well the experimental infrared spectra of CuPc and CuNO3Pc · HNO3. The agreement in the changes of line intensities during the oxidation supports the idea of ligand oxidation. This result is in agreement with the Mulliken population analysis.
