Chemical structure

Caffeine, drawn as two systems side by side: a six-membered ring and a five-membered one that share a bond. Each ring of bonds is a polygon of .side elements, each atom a satellite.

How it's built

  • Sides connect neighboring places on a ring, so six .side elements make a hexagon and five a pentagon. The double bonds of the pentagon are a second, smaller pentagon with every other side hidden.
  • Each ring of atoms is its own .gravity-spot inside a satellite as wide as the universe, so both use lanes of the same size. See gravity spot.
  • The hexagon's satellite sits two lanes left of the center, the pentagon's on orbit-3 shrink-35 to the right: the distance at which the two rings share a bond. --o-force: 150cqmin makes the reach larger than the universe, so the molecule fills the frame.
  • Atoms are satellites at fixed angles. Their background is the page color, which hides the bonds behind each letter.
  • Single bonds to the outside are vectors at angle-N; methyls and oxygens ride on orbit-6, spread over half the circle with range-180 ccw fit-range.

Benzene, pyridine or furan use the same parts with a different number of sides.
