New calculations reveal hidden pathways that let chemical reactions produce different products
Source: Phys.org - latest science and technology news stories · Published
Chemical reactions are often understood as molecules crossing a high-energy saddle point, known as a transition state, before following a downhill pathway toward a product. Conventional quantum chemical calculations typically trace this single pathway to determine how a reaction
