rm: Single bond length of Carbon – Carbon.

r′m: Single bond length of Carbon –Oxygen.

r’‘m: Double bond length of Carbon – Carbon.

rm/r1: Geometrical factor.

The absence of √2 diameter and presence of the geometrical factor corresponds to ∼√3 and ∼2 diameter demonstrates the presence of an irregular unit cell with icosahedral symmetry (Frank unit) in solid state PEG.
