Discover the scientific methods used to determine atomic structure, including X-ray crystallography and spectroscopy.

400 views

Atomic structure is determined using various scientific techniques such as X-ray crystallography, where X-rays are diffracted through a crystal to reveal atomic positions. Spectroscopy methods, like nuclear magnetic resonance (NMR), analyze how nuclei in a magnetic field absorb and re-emit electromagnetic radiation. Electron microscopes also visualize atoms directly, providing detailed views of atomic arrangements.
