Deep Learning of Activation Energies [PDF]
The Journal of Physical Chemistry Letters, 2020 Quantitative predictions of reaction properties, such as activation energy, have been limited due to a lack of available training data. Such predictions would be useful for computer-assisted reaction mechanism generation and organic synthesis planning.
