11. The Gaussian curves represent the distribution of this interaction energy . 12. It is not part of the interaction energy but enters the chemical potential directly. 13. The interaction energy between a charge and an electric dipole p is given by 14. The interaction energy is the negative of the interaction Lagrangian. 15. For example, the spin-orbit interaction energy is given by 16. At these temperatures, the available thermal energy simply overcomes the interaction energy between the spins. 17. First, one considers an energy functional that doesn't explicitly have an electron-electron interaction energy term, 18. The final component of the total interaction energy is the solvation repulsion which is as follows: 19. Intuitively is the interaction energy of the system. 20. NBO calculations have shown that transition state distortion increases the interaction energy by 2.8 kcal / mol.
