The additional peaks observed at 675-750 nm, 860-925 nm, 975-1025 nm, 1110-1180 nm, and 1450-1520 nm with oscillations ranging from 0. 0001 oscillations to 0.0016 oscillations suggest that the N-Pt-N phenalene derivative exhibits absorption characteristics extending into the nearinfrared (NIR) region. These peaks are indicative of lower-energy electronic transitions, which are likely to involve deeper electronic states or more localized excitations within the material's structure. The NIR absorption indicates the material's capacity to absorb photons beyond the visible spectrum, which may enhance its ability to capture energy from a broader range of sunlight, including longer wavelengths that are typically less utilized in photocatalytic processes. The relatively lower intensities of these peaks suggest that the material may not absorb as efficiently in these regions as it does in the visible spectrum; however, it still offers the potential for utilizing a broader portion of the solar spectrum, thus contributing to an extended absorption profile and improved light-harvesting efficiency. This augmented absorption range serves to enhance the model's optical properties, thereby enabling its engagement in photocatalytic reactions under a more extensive array of lighting conditions.
