Direct measurement of excited-state lifetimes of far-infrared collective modes in transmembrane proteins was presented. Anharmonic interactions with normal modes for energy exchange were used to achieve excitation and relaxation of collective modes. Time-resolved picosecond far-infrared pump/probe was used to measure relaxation rate of excited collective modes. The results suggested that the glassy state in colloids was obtained by the deionization of charged colloids to small amount of pressure crush.
