Abstract
Photoinduced absorption spectra of trans-(CH)x and -(CD)x between 15 and 8000 cm-1 are presented. The data demonstrate that the photoexcitations result in charged solitons which are pinned. The isotope shifts observed in trans-(CD)x provide new information about the internal modes of the excitation. Saturation of the signal at low levels is discussed in terms of a photoassisted decay channel.
