Re: [QE-users] How to specify starting magnetization for different intermediate images in a single NEB input

Dear Parveen Rawal In my opinion, you can report everything you calculate if you clearly explain what you do and why. At first glance it seems reasonable to assume that the transition state of O2 activation is at the crossing of the two paths. HTH Giuseppe Quoting PARVEEN N/A : Thank y

Thank you Prof. Giuseppe Mattioli. I have a minor question regarding constraint magnetization. Can we report the numbers obtained from constraint magnetization calculations? Like in my case, I am trying to find a TS for O2 activation over a surface which I am unable to find using starting magnetiza

Dear Parveen Rawal It depends on the system, whose physics you only know. It seems possible that a triplet ground state evolves in a different singlet ground state through the minimum energy path represented by the two low-energy branches of the two paths (the triplet one on the left of

Thank you very much Prof. Giuseppe Mattioli for your answer. I have tried to calculate pathways using both spin states. Indeed, there is a crossing between the two spin surfaces (attached picture). My follow up question is how I can determine the minimum energy crossing point out of these two surfa

Dear Parveen Rawal AFAIK, an effective and correct way to deal with the crossing of different spin surfaces in ground state calculations is to calculate the whole path twice, using both spin states, in order to evaluate where the crossing happens. I suppose you cannot constraint magnetiz
