Re: excited states of a diatomic molecule

Alex Granovsky

Dear David,

The most advanced methods implemented in Firefly for this and similar
purposes are XMCQDPT2 and SOCI (second order CI). These methods are
both post-MCSCF methods. I have created a couple of samples for NO
molecule for you, they are attached.

Kind regards,
Alex Granovsky

>I would like to calculate and investigate excited states of NO diatomic molecule as a starting point to learn what to do with my larger system. Actually I want to draw energy of these sates and see what a photon can do with this molecule; dissociates it or whatever else. As I know I can use MCSCF method to do so but it seems that other advanced methods were implemented in FF any comment to choose the method ? Is there any manual or example for such calculations ? at the end I want to draw a graph of energy of the states like 1A, 2E that is customary in spectroscopy text books. any example to help it ?  

>Many Thanks, David
