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
