Abstract: 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-Fulcher 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.
