Molekyylirakenteen, often translated as molecular structure, refers to the three-dimensional arrangement of atoms within a molecule. This arrangement dictates a molecule's physical and chemical properties, influencing everything from its melting point and solubility to its reactivity and biological function. Understanding molecular structure is fundamental in chemistry and related fields.

The study of molecular structure involves determining the types of atoms present, the number of each atom, and how they are connected by chemical bonds. These bonds can be covalent, ionic, or metallic, and their nature significantly impacts the overall structure. Furthermore, the geometry around each atom, influenced by electron repulsion as described by the VSEPR theory, contributes to the molecule's shape. Bond lengths and bond angles are specific parameters that define the precise spatial relationships between atoms.

Techniques such as X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and electron diffraction are crucial for experimentally determining molecular structures. Computational methods also play a vital role, allowing scientists to predict and model molecular structures and their properties. The concept of molecular structure is not limited to simple molecules; it extends to complex macromolecules like proteins and DNA, where intricate structures are essential for their functions. The study of how molecular structure relates to function is a cornerstone of fields like medicinal chemistry and materials science.
