What is spectroscopy in simple terms?
Spectroscopy is the study of the absorption and emission of light and other radiation by matter. It involves the splitting of light (or more precisely electromagnetic radiation) into its constituent wavelengths (a spectrum), which is done in much the same way as a prism splits light into a rainbow of colours.
What is spectroscopy used for?
Spectroscopy is used as a tool for studying the structures of atoms and molecules. The large number of wavelengths emitted by these systems makes it possible to investigate their structures in detail, including the electron configurations of ground and various excited states.
What is spectroscopy and why is it important?
Spectroscopy is used in physical and analytical chemistry to detect, determine, or quantify the molecular and/or structural composition of a sample. Each type of molecule and atom will reflect, absorb, or emit electromagnetic radiation in its own characteristic way.
What is Spectroscopy and its types?
Spectroscopy can be defined by the type of radiative energy involved. These interactions include absorption, emission, resonance spectroscopy, elastic and inelastic scattering. The materials used can also define the spectroscopy type, including atoms, molecules, nuclei and crystals.
What is the basic principle of spectroscopy?
The basic principle shared by all spectroscopic techniques is to shine a beam of electromagnetic radiation onto a sample, and observe how it responds to such a stimulus. The response is usually recorded as a function of radiation wavelength.
What are the advantages of spectroscopy?
Spectroscopy is used in physical and analytical chemistry because atoms and molecules have unique spectra. As a result, these spectra can be used to detect, identify and quantify information about the atoms and molecules. Spectroscopy is also used in astronomy and remote sensing on Earth.
What is an example of spectroscopy?
Spectroscopy now covers a sizable fraction of the electromagnetic spectrum. An example of particle spectroscopy is a surface analysis technique known as electron energy loss spectroscopy (EELS) that measures the energy lost when low-energy electrons (typically 5–10 electron volts) collide with a surface.
What is the basic principle of UV Visible Spectroscopy?
The Principle of UV-Visible Spectroscopy is based on the absorption of ultraviolet light or visible light by chemical compounds, which results in the production of distinct spectra. Spectroscopy is based on the interaction between light and matter.
Who discovered spectroscopy?
Generally, Sir Isaac Newton is credited with the discovery of spectroscopy, but his work wouldn’t have been possible without the discoveries made by others before him.
What is difference between spectrophotometry and spectroscopy?
Spectrophotometry is a method of measuring how much light a chemical substance absorbs. Spectroscopy studies the absorption and emission of light by matter, and has expanded to include interactions between electrons, protons, and ions.
What is the range of UV spectroscopy?
In UV/Vis/NIR spectroscopy the ultraviolet (170 nm to 380 nm), visible (380 nm to 780 nm), and near infrared (780 nm to 3300 nm) are used.
What is the application of UV spectroscopy?
UV absorption spectroscopy can be used for the quantitative determination of compounds that absorb UV radiation. UV absorption spectroscopy can characterize those types of compounds which absorbs UV radiation thus used in qualitative determination of compounds.
