Sterioparametrit refers to stereochemical parameters used to describe the spatial arrangement of atoms in molecules. These parameters are crucial for understanding and predicting the physical and chemical properties of compounds, particularly in areas like organic chemistry, biochemistry, and materials science.

Key stereoparametres include chirality, enantiomeric excess, diastereomeric ratio, and conformational analysis. Chirality describes molecules that are non-superimposable on their mirror images, existing as a pair of enantiomers. Enantiomeric excess quantifies the degree to which one enantiomer is present in a greater amount than the other. The diastereomeric ratio indicates the relative amounts of different diastereomers, which are stereoisomers that are not mirror images. Conformational analysis focuses on the different spatial arrangements (conformations) that a molecule can adopt due to rotation around single bonds, and how these conformations affect reactivity and stability.

The determination and application of stereoparametres often involve spectroscopic techniques such as Nuclear Magnetic Resonance (NMR) spectroscopy, as well as X-ray crystallography. Understanding these parameters is vital for drug development, as different stereoisomers can have vastly different biological activities and toxicities. In materials science, stereochemistry can influence the properties of polymers and liquid crystals.
