Ab initio static and dynamic (hyper)polarizability calculations at the time-dependent coupled-perturbed Hartree-Fock level have been carried out on polyyne, all-trans polyacetylene (PA), and trans-transoid polymethineimine by a noniterative method. The dependence on basis set and on the number of neighboring unit cells exactly included has been investigated. The 6-31G basis set with nine neighboring unit cells, and long-range Coulomb interactions taken into account, was utilized in the final calculations. Although in many instances our results are the first that have been obtained we compare with oligomer calculations wherever possible. For PA the theoretical result is also compared with experiment and the main reasons for the existing discrepancy are addressed.
