Chemcraft is a graphical program for working with quantum chemistry computations. It is a convenient tool for visualization of computed results and preparing new jobs for the calculation.
The main capabilities of the program include:
- Rendering 3-dimensional pictures of molecules by atomic coordinates with the possibility to examine or modify any geometrical parameter in the molecule (distance, angle)
- Visualization of Gamess, Gaussian, NWChem, ADF, Molpro, Dalton, Jaguar, Orca, QChem output files: representation of individual geometries from the file (optimized structure, geometry at each optimization step, etc), animation of vibrational modes, graphical representation of gradient (forces on nucleus), visualization of molecular orbitals in the form of isosurfaces or colored planes, visualization of vibrational or electronic (e.g. TDDFT) spectra, possibility to show SCF convergence graph, and some other features;
- Different tools for constructing molecules and modifying molecular geometry: using standard molecular fragments, "dragging" atoms or fragments on the molecule's image, utility for setting a point group, and other possibilities;
- Producing publication-ready images of molecules in customizable display modes, containing required designations (labels, lines, etc)
- Some additional utilities for preparing input files: visual construction of Z-matrixes, automatic generation of input files with non-standard basis sets, converting MOs read from an output file into the format of input file.
Useful software for crystallographers.
