Abstract
Electronic dephasing dynamics of HITCI in ethylene glycol are investig ated by degenerate femtosecond transient absorption spectroscopy. Puls e width and wavelength are varied to change the relative contributions of the coherent and population bleaching terms to the overall transie nt signal. Results from fitting the experimental data to a multi-mode Brownian oscillator model are presented. The data are also compared wi th photon-echo measurements.
