Todor Dudev,Mike Devereux, Markus Meuwly, Carmay Lim, Jean‐Philip Piquemal and Nohad Gresh present on page 285 (DOI: 10.1002/jcc.23801 ) a new parametrization of thewell‐established, polarizable SIBFA force field for the series of Li + —Cs + alkali cations, which are of outstanding importance in a diversity of biochemical and bioinorganic processes. With direct application to the study of cation selectivity, illustrated here by Na + at the mouth of a sodium ion channel, the delicate balance between different competing structures waswell accounted for using polarizablemolecular mechanics for the series of test complexes included in the study.
