Open Source Chemistry Software

Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science and related areas. It offers a flexible rendering framework and a powerful plugin architecture.

Program for viewing, editing, manipulating, and analyzing absorbance spectra. Simple arithnetic includes making linear combinatins of up to 10 spectra. Advanced functions include fitting spectra as LC of standard basis spectra, singular value decomposition, Fourier transform, differentiation, integration, global fitting of 3D titration and kinetic data. Graphics features allow composing Figures and export to postscript files which can be converted to pdf, imported into photoshop for rasterization, or used in page design software like Illustrator.

This application is intended to help students with the basics of chemistry. It can solve basic gas laws equations, and find the molar mass of a compound or element. These tasks allow students to cut the repetition out of basic chemistry.

GLARE is a library and a software for product based optimization of reagent lists in the context of a chemical combinatorial library design. Large virtual combinatorial libraries containing 10^12 products have been optimized within a second.

The JChemPaint Applet and Swing Application are Java programs for drawing 2D chemical structures like those found in most chemistry textbooks. It is based on the Chemistry Development Kit (cdk.sf.net). Downloads, tracker, and source code repository can be found on https://jchempaint.github.io

MSGraph is a program designed for the interactive, fast, qualitative analysis of mass spectrometric (MS) data. It is a tool to provide fast and simple access to all the information contained in an LC/MS analysis run.
