Abstract
We investigate the capacities of local measures of free volume in liquids to predict basic aspects of the fluids state- the formation of a liquid from a gas, complex 'caged' fluid dynamics and vitrification. Specifically, we investigate the capacity of the 'rattle' free volume (the volume swept out by the particle holding others fixed and cavity free volume. These quantities can be estimateds by quasi-elastic neutron scattering and positron annihilation spectroscopy. The rattle and cavity free volumes extrapolate to zero at random close packing where experimental data predicts an extropolation of the viscosity to infinity. The caging density is identified by the point where spontaneous void formation no longer occurs as a random event.Citation
