Polarization along the chain

The strong one-photon absorption is observed for polarizaion parallel to the chain axis (7). Our polarization studies of the three-wave mixing demonstrate that the two-photon absorption observed in these experiments is also polarized along the chain axis. [Pg.205]

Two-photon absorption (TPA) from G to A corresponds to Im i-(o, (o,-Condon approximation for the most divergent term, designated as a( w) for a single A state, is [90]... [Pg.181]

Major features of the optical reflectance spectra [18] are the characteristic PDA absorption band strongly polarized along the chain direction and a near infrared charge transfer band involving the polymer chain and the electron deficient pyridine rings. A similar charge transfer band has recently been reported for a different PDA [19]. [Pg.205]
