Open Babel - The Open Source Chemistry Toolbox

  •        332

Open Babel is a chemical toolbox designed to speak the many languages of chemical data. It is an open, collaborative project allowing anyone to search, convert, analyze, or store data from molecular modeling, chemistry, biochemistry, or related areas.

It can

  • Read, write and convert over 90 chemical file formats
  • Filter and search molecular files using SMARTS and other methods
  • Supports molecular modeling, cheminformatics, bioinformatics
  • Organic chemistry, inorganic chemistry, solid-state materials, nuclear chemistry

thermo - Thermodynamics and Phase Equilibrium component of Chemical Engineering Design Library (ChEDL)

  •    Python

Thermo is open-source software for engineers, scientists, technicians and anyone trying to understand the universe in more detail. It facilitates the retrieval of constants of chemicals, the calculation of temperature and pressure dependent chemical properties (both thermodynamic and transport), and the calculation of the same for chemical mixtures (including phase equilibria) using various models. Thermo runs on all operating systems which support Python, is quick to install, and is free of charge. Thermo is designed to be easy to use while still providing powerful functionality. If you need to know something about a chemical or mixture, give Thermo a try.
