Configuration interaction calculations of the excited states of polyenes C H N N+2(N=4r 6,8, 10 and 12) and (Si), (m=3-7) segments have been performed within the framework of the Pariser-Parr-Pople approximation. Characteristics of the higher twophoton state, n 'Ap in these oligomers are discussed b
It has been found that higher excited states, populated by two-photon absorption, ionize with an effkiency which, in the energy range of 5.3-6.4 eV, is independent of the energy of the excitation. This behavior is similar to that observed in sequential twostep excitation (exciton photoionization) an
