Radial distribution function g(r)iThe density of
atom pairs at separation r, normalised so a uniform structure sits at 1. Computed with
periodic images out to the smaller of 10 Å and half the cell's thinnest width. The first
peak is the bond length, the second the first-neighbour shell; where the curve settles to
1 the structure has lost all order. Dashed line: the 1.8 Å bond/CN cutoff. Dotted lines:
graphite (1.42 Å) and diamond (1.54 Å) first-neighbour distances. Brush a range of r to
highlight every atom pair at that separation in the cloud — available to 5 Å, capped at
120,000 pairs — and click outside the band to clear. With a sequence active, the other
stages draw as gray ghost curves.
