Abstract: The singlet vertical excited states of free-base porphin (FBP) have been investigated by TDDFT, ZINDO and INDO/S. The results show that both ZINDO and INDO/S could be effectively applied to the calculation of the low-lying excited states of large biological chromophores.

Key words: Singlet vertical excited states, TDDFT, INDO/S, ZINDO
