Explore Wavefunction's Spartan offerings for the Macintosh operating system below:   SpartanModel is an "Electronic Model Kit". Making use of computer technology, SpartanModel replaces the "plastic models" used by past generations of organic chemistry students, and extends the utility of molecular models in chemistry education. Spartan Student Edition is a serious molecular modeling package for teaching and learning, chemistry. Combining Spartan's easy to use graphical interface with a targeted set of computational engines, the Student Edition provides fundamental molecular modeling utilities supporting the organic chemistry curriculum. Spartan Student Physical Chemistry Edition provides students and instructors with research quality computational methods including Hartree-Fock Molecular Orbital, Density Functional Theory (DFT), and Møller Plesset (MP2) from an intuitive user interface, supporting the modern Physical Chemistry curriculum. The new Physical Chemistry Edition is a Q-Chem collaboration. Spartan Essential Edition includes a full range of molecular mechanics and quantum chemical methods, up through and including Hartree-Fock Ab Initio methods, behind the cutting-edge Spartan graphical interface putting powerful calculations at your fingertips. This version of Spartan is commonly used in academic computer labs. Spartan is the most sophisticated version offered. This program offers all features and methods included in the Essential Edition AND in collaboration with Q-Chem, enables a full range of post-Hartree-Fock approaches including Density Functional theory, Møller Plesset, and an assortment of Advanced Correlated methods. Spartan is the dominant version used in academic, government, and commercial research.
