Program CapabilitiesEnergy-related properties (cont’d)Numerical hessians from finite differences of analyticgradientsFully numerical derivatives for all methodsSaddle point (TS) search (requires hessian)Minimum energy path=Intrinsic Reaction CoordinateSeveral IRC options - GS2 is most effectiveRequires frequency input, gradients along pathFollow reaction path from reactants through TS toproductsBuild reaction path Hamiltonian (RPH):dynamics12
Program CapabilitiesEnergy-related properties (cont’d)Dynamic reaction coordinate (DRC)Add kinetic energy to system at any geometryAdd photon(s) to any vibrational modeClassical trajectory using QM-derived energiesRequires gradientsMonte Carlo sampling: find global minimumMolecular dynamics (in progress)13
