1 December 1997 Near-infrared ps transient photoinduced absorption in conjugated systems
Author Affiliations +
We demonstrate the use of a color center laser in a pump- and-probe correlation technique which enables us to extend the probe spectral range into the infrared. As a result, we find strong photoinduced infrared absorption in several (pi) -conjugated polymers and oligomers. We associate this absorption with optical transitions in the singlet exciton manifold.
