Concept Info

NAME

Structure determination

DESCRIPTION

Structure determination is a procedure by which the three-dimensional atomic coordinates of a molecule or biomolecule are solved using an analytical technique. Many techniques are used in structure determination, most commonly X-ray crystallography, NMR spectroscopy, electron microscopy and molecular modelling.

JSON-LD is the canonical representation for SciGraph data.

TIP: You can open this SciGraph record using an external JSON-LD service: JSON-LD Playground Google SDTT

44 skos:definition Atomic force microscopy (AFM), a form of scanning probe microscopy, is a technique where a cantilever with a sharp tip is systematically scanned across a sample (biological or material) surface to produce a nanometre-resolution topographic map. AFM can also be used to measure forces between the tip and sample.

127 skos:definition Nuclear magnetic resonance (NMR) spectroscopy is a technique that detects the chemical environment of atomic nuclei by the absorption of radio-frequency electromagnetic radiation when in the presence of a high magnetic field. NMR is used in chemistry and related fields for high-resolution molecular structure determination and the study of molecular dynamics.
