Reaction and Property Theory Lab
Machine-translated · View original
The lab uses quantum chemical calculations to uncover how catalysts and enzymes drive reactions.

AboutAbout the lab
Exploring the world of molecules with computation.
The Reaction and Property Theory Lab (Shiota Lab) investigates the electronic structure of molecules and the mechanisms of chemical reactions through theoretical quantum chemical calculations, without conducting experiments.
The lab believes that reactions driven by enzymes and catalysts rely on a 'mechanism' based on the movement of electrons and on spin states, and aims to uncover it and use it to design new reactions.
The lab regards calculation not as a machine that produces answers but as a tool for thinking. Members carry out research by putting into words how to choose models and what to investigate next, and organizing these points together.
Key terms
- Quantum chemistry
- A field that uses calculations based on quantum mechanics to study the electronic states of molecules and chemical reactions
- Transition metal complex
- A compound in which molecules or ions are bound to a transition metal atom. In this lab, these compounds are studied as the agents that carry out catalytic reactions
- Density functional theory (DFT)
- One of the quantum chemical calculation methods for computing the electronic states of molecules. It is also called DFT, after the initials of its English name

Based on the principles of quantum mechanics, the lab uses theoretical calculations to study chemical transformations catalyzed by transition metal complexes. It aims to uncover the 'mechanisms' of catalysts and enzymes and apply them to design new reactions.
*Illustrative imageMechanism of Methane Oxidation
Converting methane into liquid methanol is industrially important, but industrial conversion consumes large amounts of energy. Enzymes in nature are known to carry out this reaction under physiological conditions, and the lab uses theoretical calculations to study how methane is activated in gas-phase iron oxide ions, zeolites, and enzymes.
*Illustrative imageMechanism of Nitrogen Oxide Reduction
Reactions that reduce nitric oxide and nitrite are involved in denitrification in the nitrogen cycle and in exhaust gas purification, but many aspects of their detailed reaction mechanisms remain unresolved. Focusing on reactions with copper complexes, the lab uses density functional theory calculations to study how these reactions proceed.
