What it is Filled

An electrically neutral group of two or more atoms held together by chemical bonds, such as H2O, O2 or large biomolecules; the smallest unit of a substance that keeps its chemical properties.

Why it exists Filled

Let an agent handle molecules by composition, structure, properties, identifiers and representation.

Distinguishing features Filled

  • Bonded group of atoms
  • Neutral overall
  • Defined composition
  • Property of a substance

What robots and AI may and may not do Filled

Must not

  • Help design, make or use molecules intended to harm people, such as chemical weapons or poisons.
  • Present unverified predicted properties as measured facts.
  • Give health claims for molecules that the evidence does not support.

Only with a human decision

  • Ordering or synthesising new compounds.
  • Sharing research on compounds of concern.

May

  • Describe molecules, their structures and properties from chemistry databases, citing them.
  • Model molecular structures for teaching and legitimate research.

Moral aspects Filled

  • Molecular knowledge underpins medicine and industry and can also be misused.
  • Toxicity data protects workers and consumers when reported honestly.

Who is affected

  • Researchers and students
  • Workers handling chemicals
  • The public

Owners Filled

Steward

Nobody: a concept of chemistry held in common; chemical databases record known molecules.

Master systems

  • Chemical substance registries

Links to other meta-models Filled

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.molecule
  • Wikidata: Q11369 (https://www.wikidata.org/wiki/Q11369)
  • InChI: IUPAC identifier structure
  • CAS Registry Number: numeric substance

Direct properties required Filled

  • Molecular mass: Da - Molecular mass is determined from isotopic composition or measured using mass spectrometry with appropriate interpretation of detected ions.
  • Molecular dimensions: nm - Dimensions are estimated from structural measurements or molecular models using a stated geometric definition and conformation.
  • Electric dipole moment: D - The molecular dipole moment is determined by spectroscopy or calculation for a specified molecular state and conformation.

Recognition required Filled

  • Molecular formulas and structures
  • Identifiers such as InChI and SMILES
  • Ions and ionic lattices are related but different
  • Invisible to the eye; shown as formulas, models and computer structures.

Capabilities and actions required Filled

  • identify molecules by formula and name
  • describe structure and bonding
  • look up properties in databases
  • represent molecules in software

Hazards and failure modes required Filled

  • Confusing molecules and ions
