Spartan is a molecular modelling and computational chemistry application from Wavefunction. [2] It contains code for molecular mechanics, semi-empirical methods, ab initio models, [3] density functional models, [4] post-Hartree–Fock models, [5] and thermochemical recipes including G3(MP2) [6] and T1. [7]
The Chemistry Development Kit (CDK) is computer software, a library in the programming language Java, for chemoinformatics and bioinformatics. [4] [5] It is available for Windows, Linux, Unix, and macOS. It is free and open-source software distributed under the GNU Lesser General Public License (LGPL) 2.0.
ChemDraw is a molecule editor first developed in 1985 by Selena "Sally" Evans, her husband David A. Evans, and Stewart Rubenstein [1] [2] (later by the cheminformatics company CambridgeSoft). The company was sold to PerkinElmer in 2011. [ 3 ]
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods.
[1] Installation typically involves code (program) being copied/generated from the installation files to new files on the local computer for easier access by the operating system, creating necessary directories, registering environment variables, providing a separate program for un-installation etc. Because code is generally copied/generated in ...

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
There's a winamp plugin that lets it play m4a. So you can use winamp to play them, or you can use winamp to decode it to a wav (and then you can use any of a dozen programs to reencode it as an mp3) Raul654 10:58, 1 December 2005 (UTC) However, note that every time you convert from one lossy format to another, it sounds a little worse. Encoding ...
