Photoinduced infrared absorption spectra have been measured from poly(2,5-thienylenevinylene) by the phase-modulation method with modulation frequencies between 0.8 and 15 kHz. The modulation-frequency dependencies of the intensity and phase delay of the photoinduced infrared absorption have been numerically simulated by the use of a model based on second-order kinetics involving a neutralization recombination process between the positive and negative polarons. This numerical method is useful in analysing the nonlinear response associated with a bimolecular process.
