The Electronic Spectra of Phthalocyanine Radical Anions and Cations ( Book )
1 edition published in 1985 in English and held by 1 library worldwide
The oxidation and reduction of metal phthalocyanines give rise to at least six oxidation states whose electronic spectra are rationalized in some depth in terms of SCF energies, Coulomb and exchange integrals. It is shown that a single set of parameters can reproduce the Q band energies moderately well. Further this same set of energies can reproduce differences in electrochemical potentials observed within this redox set. The pattern of variation in the Q band energies (and in their number) now provides a means for identifying whether it is the metal or the phthalocyanine ligand which is reduced upon addition of an electron to the system.
Picosecond Flash Photolysis: Transient Absorption in Sn(IV), Pd(II), and Cu(II) Porphyrins ( Book )
1 edition published in 1974 in English and held by 1 library worldwide
From picosecond flash photolysis and spectroscopy, the absorption spectra of the first excited singlet S(1) and of the first excited triplet T(1) of (OEP)SnCl2 (Octaethylporphinatotin dichloride) are determined. The triplet quantum yield is determined. Similar S(1) and T(1) phototransient absorption spectra occur in (OEP)Pd. However, two Cu porphyrins show only one phototransient absorption spectrum. T(1) absorption results are generally consistent with the available earlier spectroscopic studies made with other techniques. (Modified author abstract).
