Question

What is mossbauer spectroscopy discuss its principle and application?

Answer 1

Explanation:

The Mössbauer spectroscopy is used in mineralogy to examine the valence state of iron, which is found in nature as Fe0 in metal form, Fe2+ ions and Fe3+ ions and the type of coordination polyhedron which is occupied by the iron atoms (trigonal, tetrahedral, octahedral, etc.).

Principle

The Mössbauer effect is applied to the study of minerals which relies on the fact that 57Fe, which is a decay product of 57Co, is unstable. 57Fe decays and gives gamma ray (γ-ray) and other types of energy.

Applications

Mössbauer spectrometers are used to identify minerals. However, this application because many different minerals can have site geometries that are the same resulting in the similarities in their Mössbauer spectra and the resultant peak parameters.

Answer:

PRINCIPAL OF MOSSBAUER SPECTROSCOPY:

• Mossbauer spectroscopy is a spectroscopic method primarily based totally on the Mossbauer effect. This effect, observed via way of means of Rudolf Mossbauer (once in a while written "Moessbauer", German: "Mobbauer") in 1958, includes the almost recoil-loose emission and absorption of nuclear gamma rays in solids. The consequent nuclear spectroscopy technique is exquisitely touchy to small modifications withinside the chemical surroundings of positive nuclei.
• Typically, 3 styles of nuclear interactions can be observed: the isomer shift because of variations in close-by electron densities (additionally known as the chemical shift in older literature), quadrupole splitting because of atomic-scale electric powered area gradients, and magnetic Zeeman splitting because of non-nuclear magnetic fields.
• Due to the excessive strength and extraordinarily slender line widths of nuclear gamma rays, Mossbauer spectroscopy is a noticeably touchy method in phrases of strength (and as a result frequency) resolution, able to detect modifications of only a few elements in 1011.
• It is a way absolutely unrelated to nuclear magnetic resonance spectroscopy.

APPLICATION OF MOSSBAUER SPECTROSCOPY:

• össbauer spectroscopy is a flexible method that may be used to offer facts in lots of regions of technological know-how consisting of Physics, Chemistry, Biology, and Metallurgy.
• It can supply very particular facts approximately the chemical, structural, magnetic, and time-established houses of a material.
