WebOct 15, 2015 · Fixing the bond angle to a set value seems like an extreme solution to this problem. It is. To be honest, fixing parameters in a calculation is almost always no solution at all. The resulting geometry has little to no meaning and all derived properties are for a purely hypothetical case. WebFeb 27, 2024 · The position of the current atom is specified by giving the length of the bond joining it to atom1, the angle formed by this bond and the bond joining atom1 and atom2, and the dihedral (torsion) angle formed by the bond joining atom2 and atom3 with the plane containing the current atom, atom1 and atom2. See Constructing Z Matrices for details.

However, you can … WebAug 21, 2024 · The first CV fluctuates close to zero, with fluctuations smaller than 0.2. The second is around 2.8. The fluctuations are smaller due to the stiffness of the three NO bonds. The coordination of H to C is also typically zero, but it can change a lot when the molecules approach the layer, even if there is no dissociation of H and no binding to C.
