Dear all,
I am trying to fit a bending force constant using DFT calculations. My
system is the Fe-heme prostetic group, the Fe atom is bounded to 4
N(pirrolic) in the heme-plane, the N(proximal His) and the O2 molecule.
I have calculated the energy for configurations with different values of
the N(pirrolic)-Fe-O angle. The problem is that, while I change this
angle, the angle N(His)-Fe-O is also changed. Since I need to separate
the energy contributions of this two angles, how can I fit each angle
force constant using the DFT calculations?
Thanks in advance,
Sebastian Fernandez Alberti
