Abstract

Excited electronic states of Zn-porphyrin (pi) -radical anions are studied by methods of picosecond absorption spectroscopy and quantum chemistry. An optical absorption spectrum of Zn-octaethylporphin (pi) -radical anions in its lowest excited doublet D₁ state is obtained experimentally. Excited states energies are calculated by CNDO/S-CI method. Two allowed transitions from the D₁ state are found in calculated spectrum. These theoretical data agree with the experimental spectrum which exhibits two absorption bands at ca. 500 and ca. 600 nm.
