The nature of the Soret bands and higher excitations in the UV spectroscopy of porphines has been a source of interest for many years. Theoretical studies at a singles only level of configuration interaction (CIS) succeed for visible excitation energies but fail to unambiguously predict the disposit
All-valence-electron SCF MO CI calculations of the spectra of dianion and free base porphin were performed. Comparisons are made with other SCF MO CI calculations and with experiment. The results obtained are seen to be in reasonable agreement with experiment. Characteristics of the calculated ba
