WebThe enthalpy of formation is the standard reaction enthalpy for the formation of the compound from its elements (atoms or molecules) in their most stable reference states. We report formation energies at 0K only based on energies directly obtained from the DFT especially with OptB88vdW functional. WebThis is what you call "frozen phonon", and in this method you calculate the forces in DFT, and then calculate the derivative of the forces by finite difference methods. Therefore, the numerical approximation is that of approximating a … alimemazin evolan theralen
