Vibrational Dynamics in Molecular Condensed Phases With The Clio Free Electron Laser
Single color pump-probe and photon-echo experiments have been performed on the CO stretching mode of W(CO)6 at about 1983 cm-1 in various liquids and solid environments. Combined with absorption data, the measured T1 and T2 times suggest the following conclusions: in all liquids studied, the IR absorption band is homogeneously broadened, whereas, inhomogeneous broadening is observed in solid matrices and in a xerogel. At low temperature, the echo decay is much faster in methane than in argon host.
