1 1 Calculation of Radial Distribution Function (g(r)) by Molecular Dynamic

2 2 Molecular dynamics (MD) is a computer simulation of physical movements of atoms and molecules in the context of N-body simulation.

3 3 Radial Distribution (pair correlation) Functions (RDF) Are the primary linkage between macroscopic thermodynamic properties and intermolecular interactions of fluids and fluid mixtures.

4 4 The Kronecker delta The set of number of molecules The total potential energy of the system The configurational integral
