单词 | morse potential |
释义 | > as lemmasMorse potential attributive and in the genitive, esp. in Morse equation, Morse potential. Designating or relating to the potential energy of a two-atom molecule as a function of the distance between the atoms, as given by the formula V = De {1 − e−a(R−Re)}2, where De is the depth of the potential energy minimum, R the distance between the atomic nuclei, and Re the equilibrium bond length of the molecule, at which potential energy is lowest. ΚΠ 1929 Physical Rev. 34 448 The original justification for supposing that Morse's potential function..would fit the facts adequately for HCL was that the energy level formula given by Morse is of the right form. 1930 Proc. Royal Soc. A. 130 106 For hydrogen, unfortunately, the inaccuracy of U curves drawn from the Morse formula is probably appreciable. 1948 S. Glasstone Textbk. Physical Chem. viii. 574 This weakness of the Morse function is not serious, because the conditions under which the internuclear distance approaches zero are of no practical significance. 1972 C. H. DePuy & O. L. Chapman Molecular Reactions & Photochem. i. 1 This can be illustrated most simply for a diatomic molecule by means of a Morse curve. 1986 M. Rigby et al. Forces between Molecules iii. 67 Another potential energy function for which an exact solution of the Schrödinger equation is possible is the Morse potential. 1998 Chem. Physics (Electronic text) 223 229 Assuming the potential surface of a cesium dimer [Cs2], which is modeled by a Morse potential.., we calculated the third- and fifth-order response functions for various temperatures and heat-bath couplings. < as lemmas |
