The velocity autocorrelation function (VAF) is usually calculated when one wishes to analyse the vibrational or diffusive properties of a system of atoms. [...] If the motion of the atoms tends to an oscillatory pattern, the VAF will characterize the ossilations because the velocity of the atoms will self-correlate in a periodic fashion…
