dc.description.abstract	The electronic population decay time is determined to be about 500 fs in (poly-[2-methoxy-5-(2'-ethyl-hexyloxy)-p-phenylenevinylenel (MEH-PPV) using 5.7 fs pulses. The ultrafast electronic dephasing time and the self-trapping time of free exciton to form an exciton polaron is determined as 25 +/- 2 fs and 50 +/- 23 fs, respectively. Real-time spectrogram analysis reveals dynamic mode coupling among the high-frequency and low-frequency modes. The energy-ladder descent vibrational process is clarified using the first moment of the difference absorption spectrum. The phase relaxation time is calculated from the widths of the Fourier spectra of several strongly coupled modes. (C) 2013 Elsevier B.V. All rights reserved.	en_US
