Morse potential
Morse potential[′mȯrs pə‚ten·chəl] (physical chemistry) An approximate potential associated with the distance r between the nuclei of a diatomic molecule in a given electronic state; it is V (r) = D {1 - exp[ -a (r-re )]}2, where re is the equilibrium distance, D is the dissociation energy, and a is a constant. |
