| In this thesis, the electronic, vibrational, vibronic properties of free base and metal complexes of octaethyltetraazaporphyrin (OETAP) were studied by resonance Raman (RR), off-resonance FT-Raman, infrared and UV-visible absorption spectroscopies. The vibrational properties of the nickel complex of OETAP (NiOETAP), a typical four coordinated, fluorescence free D... |
