IUPAC - X-ray diffraction analysis (08771)

X-ray diffraction analysis

synonym: X-ray diffraction (XRD)

https://doi.org/10.1351/goldbook.08771

Measurement method using diffraction of X-radiation to obtain the spatial arrangement of atoms in a crystalline sample.

Notes:

Bragg reflection follows $n λ = 2 d \sin θ$ , where $λ$ is the X-ray wavelength, $d$ is the spacing between atomic planes, and $θ$ is the angle of diffraction.
Copper $K α_{1}$ radiation ( $λ = 0.154 06 nm$ , $E = 8.04 keV$ ) is typically used for routine XRD.
