摘要
We have derived a detailed atomistic model for a-compound exhibiting typical molecular features of ferroelectric liquid crystalline substances. We show that common general purpose forcefields like CHARMm need to be improved in order to reach an acceptable degree of accuracy. A generally applicable route to derive forcefield parameters using ab initio me;hods is introduced. First results of molecular dynamics simulations of smectic phases are reported.
