We examined the ultrafast response of the metallic high-temperature phase in the conducting charge transfer complex (EDO-TTF)(2)PF(6) A large reflectivity change of approximately 10% was observed when the ultra-molecular band was excited by a weak 3 1 eV ultraviolet light pulse The lifetimes of the photo-induced states were 02 and 0 7 ps in the Drude-like band and the intra-molecular band respectively Measurement of the photo-induced spectrum just after photo-excitation and simulation using the Drude model revealed tha
