Exciton-wave packet dynamics in molecular aggregates studied with pump-probe spectroscopy

Dahlbom, Mats LU ; Minami, Tatsuya ; Chernyak, Vladimir ; Pullerits, Tõnu LU ; Sundström, Villy LU and Mukamel, Shaul (2000) In Journal of Physical Chemistry B 104(16). p.3976-3983
Abstract

The doorway-window representation of sequential pump-probe spectroscopy, derived by solving the nonlinear exciton equations, is used to study exciton dynamics in molecular aggregates. Exciton relaxation is incorporated through a multilevel Redfield relaxation superoperator calculated using the Brownian oscillator spectral density for the collective phonon coordinates. Optical pulses are included using a mixed time and frequency domain (Wigner spectrogram) representation. Numerical results are presented for a five-chromophore model aggregate.
