NBO6 binary programs are now offered for a complete line of Cygwin, Linux/Unix, Mac OSX, and PC-Windows operating systems and 32- or 64-bit x86 architectures (see order form). The NBO6 distribution package is ready to "load and go" as an interactive ESS/NBO program with any NBO6-compatible ESS binary in the same directory, or as a stand-alone GenNBO program to analyze the wavefunction in a previously generated archive (job.47) file.

See the README file of the NBO6 distribution, the NBO6 Manual, and the ESS documentation for further instructions on preparing the input for each option. See the Affiliated Programs link for information on currently available NBO6-compatible ESS versions.
