rm: The position of the peaks maxima in the total radial distribution function, W(r), rm/r1,: geometrical factor (g.f).

The variation of g.f conserves the singularity of D.R.P. In this model; three atoms (trio) are in hard contact, the forth one (the apex) is free to find its exact position. In these liquids the different values of (g.f) of single bond; C-C, C-O and double bond C = C in a pentagonal chain is shown.

The experiment indicates the fluctuation of the values of the geometrical factors between √3 = (1.7320) (singularity of regular tetrahedron) and √8/√3 = 1.6329 diameter (bi-pyramid configuration). The r3/r1 shows the effect of medium range order on the local topology of the atomic network for each sample.
