The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.
