Abstract :
We investigated the transient response of the solvated electron ejected by photodetachment from potassium ferrocyanide in water using time resolved terahertz spectroscopy (TSTS). We find that the measured frequency dependent conductivity can be well described by a Drude-Smith model, supplemented by a Lorentz model oscillating near 5 THz.
