- a ⁇ 2 ⁇ represents a region characteristic in which the molecular orbitals are distributed only in one subregion of the center of the molecular orbital, and the selected extended substance E-A ⁇ 2,1 ⁇ also shows the same distribution region characteristics differently.
- the extended R-molecule orbital library can be more useful for evaluating the molecular orbital distribution region than the R-molecule orbital library because the characteristic molecular orbital distribution region characteristics are represented in various patterns due to the newly selected expansion material.
- Expanded R-molecule composed of a constituent material and an expansion material exhibiting molecular orbital distribution properties that are mutually exclusive with respect to three detailed regions shown in Example 1 to confirm the capability of evaluating molecular orbital distribution region characteristics using the MODREM of the present invention.
- the MODREM method was applied to TGT, a substance to be evaluated for molecular orbital distribution region characteristics, as shown in FIG. 11.
- TGT shows the molecular orbital distribution region characteristic indicated by A ⁇ 3 ⁇ due to the distribution of molecular orbitals only in the detailed regions at both ends, as evaluated by MODREM.
- MODREM has been shown to accurately assess molecular orbital distribution region characteristics.
- the extended R-molecular orbital library which is composed of mutually exclusive relations with various molecular orbital distribution regions, is a development of the existing R-molecular orbital library having constituents exhibiting unique molecular orbital distribution region characteristics.
- the orbital distribution region characteristics can be represented in various patterns, and thus can be used as a comparison criterion for more accurately evaluating molecular orbital distribution regions.
- a MODREM that can quantitatively evaluate the molecular orbital distribution region using the extended R-molecule orbital library and apply it in real cases to confirm the accurate evaluation of the molecular orbital distribution region of the material. This confirms the effectiveness of the MODREM method using the extended R-molecule orbital library, and extends the quantitative molecular orbital distribution evaluation method to the molecular orbital distribution area evaluation. It is expected to be used more systematically.
