Predicting molecular structures involves using quantum chemistry methods and molecular modeling software like Gaussian, or density functional theory (DFT). These tools simulate how atoms and electrons interact to form a molecule, providing insight into its geometry and properties. Scientists also use X-ray crystallography and NMR spectroscopy to experimentally determine structures, often complementing computational methods for accurate predictions.
