摘要: We examine the transport properties and dynamics of free electrons in n-hexane by means femtosecond spectroscopy using an ultraviolet pump pulse to create a THz electromagnetic as probe. The complex dielectric response photogenerated is determined over broad range frequencies, from which we infer electron scattering time density through Drude model. evolution carrier reveals nongeminate electron-ion recombination within hundreds picoseconds at high ion concentration.
