Molecule fragment

Moieties are the smallest building blocks handeded in advanced mechanosynthesis of technology level III and II. When simple resource molecules are gobbled up one always ends up with a few atoms on the tooltip at first. Afterwards it is generally not necessary to prepare it down until only one atom is left.

Except for hydrogen (and later maybe oxygen) in most cases one does not put down a single atom but a small (always bond) molecule (a moiety) with some bonds hydrogen capped and at least one open.

For mechanosynthesis of diamond ethyne C₂H₂ methane CH₄ and traces of digermane Ge₂H₆ can be used. This has been toroughly analyzed.

Further molecules of prime interest are carbon dioxide CO₂ water H₂O and nitrogen gas N₂. The capability of handling those allows for tappingn the air as a resource for products that (almost) exclusively contain diamondoid molecular elements out of hydrogen carbon oxygen and nitrogen (HCON).
