Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction (13C, 1H and other nuclei) as well as for searching spectra, structures and other properties. The nmrshiftdb2 software is open source, the data is published under an open content license. The core of nmrshitdb2 are fully assigned spectra with raw data and peak lists (we have pure peak lists as well). Those datasets are peer reviewed by a board of reviewers. The project is supported by a scientific advisory board. nmrshiftdb2 is part of the NFDI4Chem initiative (https://nfdi4chem.de/) and will provide a component for a curated repository there. Please consult the documentation for more detailed information.

ProtoFit is software for modeling the acid/base behavior of surfaces. The software is used for parameterizing surface protonation models and for visualization of potentiometric titration data.

MESMER is designed to analyze and simulate reactions in the gas phase that take place on a potential energy surface that is characterized by having one or more potential wells, and which are typically described by rate coefficients that depend on pressure (or concentration) as well as temperature. MESMER allows you to simulate systems over a wide range of pressures and temperatures, extract rate coefficients, analyze experimental data, fit model parameters and represent rate coefficients in formats that can be used directly in large scale simulations (e.g. Cantera or Chemkin).

WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, partly also classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. Allowing for visualization of dynamics 'on the fly', WavePacket is easy to use . First established in 2004, the present Matlab version is in a stable, mature state. Further development mainly by Burkhard Schmidt at WIAS and FU Berlin.
