X-Ray Diffraction (XRD)

An X-ray powder diffraction pattern is a plot of the intensity of X-rays scattered at different angles by a sample • The detector moves in a circle around the sample –The detector position is recorded as the angle 2theta (2θ) –The detector records the number of X-rays observed at each angle 2θ –The X-ray intensity is usually

UNIT 2: CRYSTAL DIFFRACTION AND RECIPROCAL LATTICE

Powder diffraction film: • The cones of distracted radiation intersect the cylindrical strips of film inline or arec and when the strips is unrolled and make it flat, the strip shows diffraction lines as shown in figure 2.8. • Each diffraction line is made up of a large number of small spots. Each line is formed by a separate crystal particle.

ELECTRON DIFFRACTION

The aluminium target is a powder of small crystal flakes, i.e., it is polycrystalline. Thus the diffraction pattern appears as rings. There are also many possible planes that may be drawn through the crystal lattice, and in a powder sample in general all of these will be present. A simple example of this is shown in Figure 1.

Energy Dispersive X-ray Spectroscopy (EDS)

• Powder Sample containing CeLaNdBaPr • Lots of heavily overlapped peaks in a small spectral range • Separating characteristic x-rays by X-ray diffraction using a crystal of known lattice spacing d • The angle of diffraction needed to collect X-rays of a particular wavelength is predicted using Bragg’s Law.

X-ray absorption spectroscopy for beginners

X-ray absorption spectroscopy The impact of the biological x-ray absorption spectroscopy (BioXAS) has increased as indicated by the number and ranking of publications Ascone et al. (2009). Journal of Synchrotron Radiation 16, 413-42. Application to physics, earth science, chemistry and biology (see presentations of Profs.
