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.
