520 |a A structure optimization method with ionization energy constraint is developed to explore structures with specific ionization energy. The Levine-Coe-Martínez penalty function (J Phys Chem B 2008, 112, 405) was adopted, and the penalty function includes a predefined core-ionization energy and inner-shell ionization energy. For an SN 2 reaction, isomerization of a platinum complex, a proton transfer reaction, and carbon monoxide adsorption on a palladium cluster, the present method was tested, and the targeted energy minima were obtained as designated by the input ionization energy. The shape of the objective function, the parameters in the penalty function, and structural changes during the optimization process were discussed. An automated parameter setting and possible problems are discussed for future direction. © 2018 Wiley Periodicals, Inc
