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 the pump; however, the spectra show parallel dichroism when the probe is polarized. The experimental results are analyzed on the basis of the β€œeffective conjugation coordinate” theory (ECC).

It is now established that the circular dichroism in vibrational transitions (v.c.d.) of chiral molecules is a measurable phenomenon'. In v.c.d. measurements (3n -6) vibrational transitions can be probed, whereas, in conventional cd. measurements in the visible region, only a few electronic transit
