WebApr 17, 2024 · Inspired by the Principal Component Analysis in statistics, we hereby present a novel framework, Principal Interacting Orbital (PIO) analysis, that can very quickly identify the “dominant interacting orbitals” that are semi‐localised and easily interpretable, while still maintaining mathematical rigor. WebJul 14, 2024 · Updated on July 14, 2024. In chemistry, the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atom's nucleus. This level is denoted by the principal quantum number n. The first element in a period of the periodic table introduces a new principal energy level.

WebClassify each orbital as symmetric (S) or antisymmetric (A) with respect to the symmetry element conserved during the reaction. Construct orbital correlation diagram connecting orbitals of starting materials with those closest in energy and of the same symmetry in the product & add electrons according to the Aufbau principle. Principal interacting orbital (PIO), based on quantum chemical calculations, provides chemists with visualization of a set of semi-localized dominant interacting orbitals. The method offers additional perspective to molecular orbitals (MO) obtained from quantum chemical calculations (DFT for instance), which often … See more A typical workflow is summarized here.
