Abstract

The magnitude and phase delay of the photoinduced infrared absorption bands of polythiophene have been measured at 78 K with a sinusoidal intensity-modulation of 514.5 nm laser light. All the photoinduced bands show the same response in magnitude and phase delay to the external stimulus. The magnitudes of the photoinduced bands show an approximate f ^0.6 dependence on the modulation frequency above 1.25 kHz. The micro- to millisecond photoexcitation dynamics are discussed.
