Abstract

Molecular radius of some pure liquids has been evaluated using various methods at varying conditions of temperatures. Sound speed and density data have been employed to compute the molecular radius and the liquids under consideration are n-hexane, n-heptane, n- dodecane, cyclohexane and toluene. A comparison has been made between the values obtained from acoustic methods and non-acoustic methods. The variation pattern of molecular radius using various methods has been studied and an attempt has been made to correlate the molecular radius with the relative merits of these methods.
