Single color pump-probe and photon-echo experiments have been performed on the COstretching mode of W(CO) 6 at about 1983 cm -1 in various liquids and solidenvironments. Combined with absorption data, the measured T 1 and T 2 times suggestthe following conclusions: in all liquids studied, the IR absorption band ishomogeneously broadened, whereas, inhomogeneous broadening is observed in solidmatrices and in a xerogel. At low temperature, the echo decay is much faster in methanethan in argon host.
