[gmx-users] activation energy

2013-01-14 Thread Ahmet yıldırım
Dear users,

Is it possible to calculate the activation energy of a structure using
Gromacs? if OK, how?

Thanks in advance

I would first explain what do you mean with activation energy. What 
definition do you use?

It is the minimum energy required to start a chemical reaction. I have a
structure complexed A and B ligands. I want to calculate how these
ligands changed
the activation energy.

OK. In a chemical reaction bonds are built or broken. None of this 
happens during a MD simulation.

structure complexed A and B ligands. I want to calculate how these
ligands changed
the activation energy.
You would probably need some kind of (ab-initio) QM calculation to study 
this. It would be a better idea to ask, e.g., the Gaussian community (in 
CCL) for advice.
