SINDO

SINDO is a suite of programs to carry out anharmonic vibrational structure calculations. It consists of programs for generating the anharmonic potential energy surface (MakePES), vibrational self-consistent field (VSCF) and post-VSCF solver (FSindo), and a visualizer (JSindo). SINDO is licensed under GNU General Public License v3.0, and is available free of charge.

JSindo is a program to visualize and to manipulate molecular vibrational modes. The program is distributed as an executable JAR file, which runs on multiplatform (Windows, MacOSX, and Linux) using Java. JSindo uses JAMA and JogAmp/Java3D as an external library. Users need to download and install these libraries to use JSindo. See the install manual in the document for more details.
