Population Spin: A population analysis of the spin properties (Table ) (Figure ) reveals that the Pt atom in the N-Pt-N phenalene derivative has a spin range of -0.165 to 0.3420.342, while the nitrogen exhibits a range of -0.003 to 0.171. These spin values offer critical insights into the optical properties of the model and its photocatalytic behavior, which is further elaborated upon in the following subsection.
