Basic correlation effects: polarizing interactions of outermost particles via the polarized core and mutual screening of outermost particles are taken into account to provide an acceptable accuracy of calculations. The paper gives refined values for the negative ions involved....
Calculations reveal [5] that such a substitution lowers the ZPVE of the complex, and of the monomer pair, by very nearly equal amounts. Consequently, this peripheral deuterosubstitution has no net effect upon the H-bond energy. It is hence concluded that replacement of hydrogen by deuterium ...
The total energy will be computed for the chosen XC functional (LDA, GGA, hybrid functionals, or Hartree-Fock). MetaGGA functionals, (ZORA) scalar relativistic and relativistic spin-orbit calculations, electric fields and QM/MM are not supported yet. In particular the requirements to the integrat...
Bond dissociation energy is only equal to bond energy fordiatomic molecules. This is because the bond dissociation energy is the energy of a single chemical bond, while bond energy is the average value for all the bond dissociation energies of all bonds of a certain type within a molecule. Fo...
In the early days of VB theory, in order to make energy calculations possible, Pauling and his contemporaries assumed that the orbitals could be considered orthogonal to each other [3,4]. This assumption resulted in a dramatic simplification for VB calculations and the resultant form of VB ...

We tested more complex tip conformations and found the effect in tip-sample interaction energy, whose gradient is proportional to the forces, is negligible (Supplementary Figure 2). The relative frequency shifts from calculations are in excellent agreement with the measured curves for both CO and ...
Understanding the energy it takes to build or break chemical bonds is essential for scientists and engineers in a wide range of innovative fields, including catalysis, nanomaterials, bioengineering, environmental chemistry, and space science. Reflecting the frequent additions and updates of bond dissociati...
