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. WebThis module complements the capabilities of the more traditional Gaussian function based approaches by having an accuracy at least as good for many applications, yet is still fast enough to treat systems containing hundreds of atoms.
