✦ Synopsis

The picosecond photoinduced absorption of a series of a-coupled thiophene oligomers in solution have been measured using the Kerr ellipsometry configuration. We present spectral and dynamic studies of the sharp transient absorption peak observed in the transparency region of these oligomers. Its origin and the reasons for its narrow line shape are discussed. The conversion towards the triplet state is observed in terthiophene.

## Abstract The photoinduced infrared spectra of stretch‐oriented polyhexylthiophene and polyoctylthiophene are reported as a function of the polarization both of the pump light and of the probe IR beam. There is no change in the intensity of photoinduced IR absorption due to the polarization of th
