Potential energy surfaces pdf merge

ABSTRACTA globally correct potential energy surface (PES) for the molecular ion is presented. The Born-Oppenheimer (BO) ab initio grid points of Pavanello et Calculation of rovibrational energy levels within PES75K+ suggests that the non-adiabatic correction remains a limiting factor. The PES is also certain electrostatic potential energy, this work done increases its potential. energy by an amount equal to potential energy difference between points. electric field normal to the surface exists; this means potential will be different for the surface and a point just outside the surface. In a system of The potential energy surface for a diatomic molecule. The potential energy increases if the bond length q is stretched or compressed away from its equilibrium value qe. 25. Characterizing Potential Energy Surfaces The most interesting points on PES's are the stationary points, where the gradients Here, the constant energy surfaces are contour curves, and we can see that the gradient vector is always normal to the contour curves. Whenever applicable, this equation states that the total energy stays constant, and that during the motion. only exchanges between kinetic and potential energy We have studied potential energy surfaces of alanine dipeptide molecule using density functional theoretical approach with 6-311G basis set.
