New theory promises faster, more accurate predictions of chemical reaction energetics

University of Illinois Grainger College of Engineering
Peer-Reviewed Publication

Researchers at the University of Illinois Urbana-Champaign have developed a new theoretical framework that could dramatically reduce the cost and complexity of predicting chemical reaction energetics without sacrificing accuracy. Led by chemical and biomolecular engineering professor Alexander V. Mironenko, the team introduces a method that may one day replace the current computational models used in quantum chemistry.
