'isotope' is a small command-line utility to calculate the isotope pattern for a given chemical formula. It allows to run calculations interactively, in batch mode, via the command line, or (using a webserver) via a web interface.

The program does nmr product operator calculations for one, two, three and four spins. Receiver phase cycling is possible in conjunction with pulse phase cycling to simulate coherence pathway selection. An extensive manual and help files are included. Currently running under Linux and Windows.

htcontrol is a software to control high-temperature single crystal XRD experiments on a STOE IPDS II or 2T diffractometer platform. A Manson SDP2210 power unit is needed as well as the ICP DAS I7019 data acquisition interface (amount of investment approx. 600 EUR). htcontrol is written in Perl and runs on a cygwin platform to be installed on the WinXP/10 host. Data collections are performed with Stoe's WinXpose (>=1.7.3) via the non-interactive XML interface. For details see: J. Appl....

The Blue Obelisk Data Repository lists many important chemoinformatics data such as element and isotope properties, atomic radii, etc. including references to original literature. Developers can use this repository to make their software interoperable.

PSI is an open-source program for computing molecular properties using high-accuracy, ab initio, quantum mechanical models.

IFEFFIT is a library and set of interactive programs for the analysis of x-ray absorption fine-structure (XAFS) data. IFEFFIT combines state-of-the-art analysis algorithms with graphical display of XAFS data, and general data manipulation. It can be

GVIB is a user friendly package for vibrational analysis. Given a molecular geometry, it will calculate vibrational frequencies and intensities using anharmonic internuclear potential.

free2bind a suite of general purpose bioinformatics tools for computing the minimum free energy (the most stable) binding between two separate RNA molecules.

CHIMP aims to provide a complete suite of tools for the investigation and modeling of chemical systems. It currently is able to parse chemical reaction mechanisms and run kinetic Monte Carlo simulations on the reacting system.
