Molecular structure is the detailed arrangement of atoms within a molecule. It refers to the spatial arrangement of atoms in a molecule and the chemical bonds between them. Determining the molecular structure of a compound is crucial for understanding its properties and reactivity. This field of research involves techniques such as X-ray crystallography, nuclear magnetic resonance spectroscopy, and computational methods to study and characterize the structure of molecules. Knowledge of molecular structure is essential in fields such as organic chemistry, biochemistry, and materials science.
