It can be operated as a polarizable continuum model for the implicit solvation effect, or operated as an ML/MM method with accurate EE to account for explicit solvation. It enables simulations on a wide range of high-quality molecular spectra, such as infrared, Raman and NMR. With FieldSchNet ML/MM, they observed a 300-fold acceleration in the reaction rate of a Claisen rearrangement in water solvent compared to gas phase.
