QEC can calculate cross sections for molecule with atoms as heavy as Ar and up to 20-25 atoms in total. However if you want to go beyond Ar you can proceed with caution. The complexity level increases for us with the number of electrons in the system. If the number of...

Q: How rotational cross section data is calculated in QEC and where can I find the results? A: QEC plots the summed cross-sections of all transitions calculated in the PolyDCS module, but not the cross-sections for the individual processes. You can find the detailed...

Q: What is the difference between the vertical excitation energy cutoff, start energy and end energy in close coupling (CC) calculations in QEC? A: The start and end energy grid define the energies of the incoming scattering electron. The vertical energy cutoff...
