Spartanfrom Wavefunction is a general purpose modelling tool that uses moderncomputational methods to provide researchers with quantitative data on amolecular structure, energy, reactivity, selectivity and a wide rangeof molecular properties. With a single GUI (graphical userinterface)/computational engine Spartan provides users with a molecularmodelling tool which is both comprehensive and user friendly. Withunsurpassed visualisation and a wide range of well documentedcomputational methods in a single user-friendly software tool, Spartandelivers the full power of molecular modelling to chemists everywhere.
