✦ Synopsis

A fluid with isotropic particles is analyzed from first principles. Below the visco-elastic transition temperature, the relaxation time for the specific heat diverges according to a Vogel-F&her law. The reason for the discovered singularity is the volume excluded by a particle. So, the singularity is of quite general nature. Formally, the classical fluid undergoes a phase transition of first order at the singularity. For o-terphenyl, the theory is in agreement with experiments. Comparisons with other properties below the melting temperature are presented and further experiments are suggested.

A brief review is presented about our recent work on computer studies of a continuum model describing spinodal decomposition of binary fluid, which quantitatively accounts for corresponding experimental results. We then switch over to discussing problems of glass transitions. First we consider the u

The phosphorescence of quinoxaline as dopant in 2-MTHF is investigated at temperatures near the glass transition of the host solution. Within the accessed time range from 500 ps to 1 s, the emission band is subject to a temporally resolved Stokes shift of z 250 cm-' monitoring the solvation dynamics
