The validation is further supported by comparisons with known interstellar molecules like formamide and methyl isocyanide, whose computationally predicted properties are consistent with observational data. This correspondence reinforces the applicability of the methodology to a diverse range of molecular systems, including chemically complex structures with branched or unsaturated components. By ensuring agreement with established data, this study demonstrates the robustness of its computational framework for predicting the properties of both known and yet-undetected interstellar molecules.
