Complex man-made molecules can decompose into detectable components, which can be identified through quality assurance methods or sensory detection. The possibility of irradiating these components with resonant energy to reveal their existence is affirmed, forming the foundation of various spectroscopy techniques, including Nuclear Magnetic Resonance, infrared, and visible/UV spectroscopy. The discussion highlights that different atomic structures can be illuminated based on their components, allowing for the injection of energy to induce reactions that expose their existence. This leads to the potential for establishing mathematical relationships regarding structural behavior prior to experimentation. Methods for calculating spectra, such as Molecular Mechanics and Hartree-Fock, can be employed, with semiempirical techniques being the most commonly used for these calculations.
