Porphyrins XXIII: Fluorescence of the second excited singlet and quasiline structure of zinc tetrabenzporphin

Porphyrins XXIV. Energy, oscillator strength, and Zeeman splitting calculations (SCMO-CI) for phthalocyanine, porphyrins, and related ring systems

“…We have recently remeasured the molar extinction coefficient in pyridine [19] and find somewhat higher values than those reported earlier [14c]. Also a weak band reported at 460 nm [14c] that has no theoretical counterpart has been shown by excitation spectra to be an impurity [19]. Vapor spectra have been taken down to ..1 ~ 200 nm [12a].…”

“…3. Experimental values for ZnTBP in vapor [12a] and octane pyridine [19] benzporphin (TBP). All are predicted to have a greater B than Q splitting, with lower energy component in each case having greater intensity.…”

Photoconduction and transport mechanisms in polycrystalline zincphthalocyanine thin films

“…In metal complexes containing the macro cycles considered here these four orbitals are assumed to be π orbitals associated primarily with the dianions. In all four dianions the lowest unoccupied orbitals are degenerate and have e g symmetry [28,[31][32][33]. Furthermore, in all four dianions the two highest occupied orbitals have a 14 and a 24 symmetry.…”

Effect of substrate temperature on the optical constants of zincphthalocyanine thin films

“…In metal complexes containing the macro cycles considered here these four orbitals are assumed to be π orbitals associated primarily with the dianions. In all four dianions the lowest unoccupied orbitals are degenerate and have e g symmetry [14,[18][19][20]. Furthermore, in all four dianions the two highest occupied orbitals have a 14 and a 24 symmetry.…”
