An open source code for the analysis of electronic excited states:
Natural Transition Orbitals;
Detachment and Attachment Density Matrices;
Quantum Chemical Charge-Transfer Descriptors.
The code is intended to postprocess Gaussian 03 and 09 outputs.
Important Note: A new release with better compilation option has been released on November the 9th 2015. We strongly advise to use this one since the previous option may have led to some unexpected bugs.
MOPlot - visualization program for fast Molecular Orbitals Plotting (and other stuff - please, read the full description) from the outputs of the Gaussian09-94, Molcas, Gamess/US, Firefly quantum chemical calculation packages.
