抜粋

Structural relaxation in liquids on a wide time scale has been studied by time-resolved transient hole-burning spectroscopy. Time evolution of a hole with a long lifetime that is due to a long triplet-state lifetime has been measured in the systems of merbromin in glycerol and propylene glycol, and also in the systems of Zn-protoporphyrin in glycerol dimethylformamide mixtures over the temperature range 180-300 K and time range 1 μs-10 ms. The temporal shift of the hole has revealed nonexponential dynamics of liquids and has been well reproduced by a stretched exponential function. The temperature dependence of the relaxation time has been compared with the results of dielectric relaxation measurements.
