Pair correlation function (PCF) is given by,

         h(r) = g(r) -1 ------------------------ [1423]

where,
          g(r) -- The Pair Distribution Function (PDF).

h(r) approaches zero at large distances, indicating no correlation, and approaches -1 at r = 0, indicating perfect negative correlation when there is no overlapping between the atoms.
