The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc.
The application of quantum mechanics to chemistry is known as quantum chemistry. Quantum mechanics can also provide quantitative insight into ionic and covalent bonding processes by explicitly showing which molecules are energetically favorable to which others and the magnitudes of the energies involved.

Some examples of 3D ray-traced caustics can be found here. The focus of most computer graphics systems is aesthetics rather than physical accuracy. This is especially true when it comes to real-time graphics in computer games [8] where generic pre-calculated textures are mostly used instead of physically correct calculations.
Figure 1: Selected area diffraction pattern of a twinned austenite crystal in a piece of steel. Electron diffraction is a generic term for phenomena associated with changes in the direction of electron beams due to elastic interactions with atoms. [a] It occurs due to elastic scattering, when there is no change in the energy of the electrons. [1]:
Diffraction gratings can also be used to produce dispersive effects; these are often used in high-power laser amplifier systems. Recently, an alternative to prisms and gratings has been developed: chirped mirrors. These dielectric mirrors are coated so that different wavelengths have different penetration lengths, and therefore different group ...
An example of a cubic lattice. Many properties of materials are affected by their crystal structure. This structure can be investigated using a range of crystallographic techniques, including X-ray crystallography, neutron diffraction and electron diffraction.
The prospective of structural chemistry lies in its ability to address real-world challenges, fuel scientific innovation, and contribute to advancements in various fields. Collaboration, technological advancements, and a multidisciplinary approach will continue to shape the future of structural chemistry, paving the way for groundbreaking ...
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering, when there is no change in the energy of the waves. The resulting map of the directions of the X-rays far from the sample is called a diffraction pattern.
