This program is a general purpose combination of the CNDO/S, CNDO/2, INDO, and INDO/S programs. It does RHF (open and closed shell) calculations only, no geomety optimizations, and does Multi-Reference CI. Transition metals are included.


The program is based on QCPE 174, but it has completely rewritten, updated and imploved by Dr. Jeffrey R. Reimers at the School of Chemistry University of Sydney NSW 2006 Australia.

The graphical user interface has been written by Dr. Baudilio Tejerina using Rappture toolkit at the Department of Chemistry, Northwestern University, Evanston, IL - USA
