The new study shows how the electron configuration and electronegativity of atoms change as pressure increases.
Electronegativity is estimated using the following the equation from EHOMO and ELUMO:
In addition, the high electronegativity of the bromine atom may form dipole-dipole interactions with the epoxy causing a reduction of free volume.
According to Koopmans' theorem, quantum chemical parameters are related to the frontier orbital energy, such as ionization potential (I), electron affinity (A), electronegativity ([chi]), hardness (n), and affinity index ([omega]).
Computed parameters such as [E.sub.HOMO], [E.sub.LUMO], energy gap ([DELTA]E = [E.sub.LUMO] - [E.sub.HOMO]), dipole moment ([mu]), absolute electronegativity ([chi]), global hardness ([eta]), and global softness ([sigma]) were calculated and shown in Table 5.
An interesting hypothesis arises: Is the amount of electron transfer between metal and phosphorene mainly depending on different electronegativity? To answer this question, a verification study is indispensable.
This Moran autocorrelation descriptor contained in the model reported in this study was defined on the molecular graphs using atomic masses (m), Sanderson electronegativity (e), and inductive effect of pairs of atom 3 bonds apart as the weighting scheme.
An attractive force occurs because oxygen has high electronegativity, and hydrogen is a nonmetallic element that has low electronegativity.
The electronegativity of the 3 groups increased gradually, which was the same as that of the LUMO.
