Question about ruecker

[ylniu]

Dear all,

I need to understand how the program "NumForce" or "ruecker" generates the coord files during frequency calculation of excited state, whenever the molecule has symmetry or has no symmetry. But the program "ruecker" is a binary file which can not be read. May I get some clues from you ?

Thanks
