It also includes a graphical user interface (GUI) that builds molecules and offers full visualization of results. AMPAC is a fully-featured semiempirical QM program.In addition to standard features, like numerically stable molecular dynamics, fast multipole method for including all atoms in the calculation of long range potentials and robust structural optimizers, it has a flexible choice of potentials and a simple yet powerful ability to manipulate molecules and analyze individual energy terms. It can manipulate both small molecules and macromolecules including proteins, nucleic acids and other polymers. AMMP is a modern full-featured molecular mechanics, dynamics and modeling program.AMMP Molecular Dynamics, Molecular Mechanics.AmberFFC is designed to convert the different existing AMBER force fields (FF) freely available in the public domain, for use with commercial molecular modeling packages, using the MSI software package as a case model.The ALOGPS program can be also used to predict logD values. ALOGPS provides prediction of logP and aqueous solubility of compounds to be used in drug design (ADMET and HTS) and environmental chemistry studies.These are a new generation of 3D-molecular descriptors with application in 3D-QSAR, QSAR, virtual screening, design of combinatorial libraries, selectivity studies and in any field where 3D quantitative pharmacophoric description for (macro)molecules is needed. ALMOND is a program specifically developed for generating and handling alignment independent descriptors called GRIND (GRid INdependent Descriptors).Several smaller utility and property programs are available for pre- and post-processing data of the main calculations. The two main programs are ADF, for molecules, and BAND for periodic structures: polymers, slabs, and crystals. ADF is the Amsterdam Density Functional program system for high-quality computational chemistry research.Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation). ABINIT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a planewave basis.2D is a numerical Hartree-Fock program for diatomic molecules.Here is only a small part of the article, for more please follow the link The text that follows is owned by the site above referred.
