Redox as Geometry: Electron-Tension Transfer in Chemical Systems

The conventional vocabulary of redox chemistry — oxidation states, reduction potentials, electron affinity, half-reactions — is a bookkeeping system. It records what electrons do in aggregate, by counting charge before and after a reaction. It does not describe what happens at the moment of transfer, at the orbital level, in three-dimensional molecular geometry. This omission is not trivial. It leaves chemists with predictive tools calibrated only to outcomes, blind to the actual geometric and orbital-level events that determine whether, how fast, and along what pathway electron density moves. This paper introduces and develops the electron-tension transfer framework as a mechanistically precise alternative. We define three core terms. Electron-tension is the orbital-geometric strain that accumulates when a molecular orbital carries more electron density than its current nuclear geometry can accommodate without distortion — it is the mismatch between the density a geometry holds and the density that geometry prefers. Tension currency is the directional gradient of that strain: it is not electrons alone that transfer, but quanta of geometric strain that drive transfer and must be absorbed, relayed, or dissipated by every acceptor in the pathway. Tension geometry is the three-dimensional orbital shape — HOMO coefficient distribution, LUMO symmetry, ligand-field splitting pattern, coordination number — that determines both the capacity of a site to hold electron density and the directionality of transfer. Together, these three terms replace thermodynamic bookkeeping with mechanistic description: electrons move because donor geometry is strained under electron load and acceptor geometry is geometrically primed to receive. We argue that this framework predicts redox behavior, failure modes, and catalytic strategies more cleanly and more specifically than existing thermodynamic language, and we develop it here across ten sections covering the full scope of electron-transfer chemistry — from simple inorganic redox to biological electron transport chains, photocatalysis, battery electrolyte decomposition, and catalyst design. This work is part of a larger collection of UST documents. The other versions available in the DOI record are not revisions of this document. They are separate papers written for different purposes. Some versions present the full mathematical proofs behind the update rules, others provide a technical physical description of substrate behavior, and others are formal proof papers built around the Universal Balance Laws. Together, these documents form a complete set: a plain‑language booklet, a physical description paper, and full mathematical proof papers, each offering a different perspective on the same underlying theory.
