Abstract
  • Electronic excitations of condensed phase eumelanin aggregates are investigated with soft X-ray spectroscopies. Resonant photoemission data indicate that mechanisms of charge delocalization may occur when electrons are excited about 3 eV above the first unoccupied electronic level. An average, lower limit value of 1.6 fs was estimated for the lifetime of the excited C 1s-pi* states. (literal)
