Editorial Note

Spectroscopy and spectrography are terminology used to describe experimental spectroscopic approaches that include measuring radiation strength as a function of wavelength. Spectrometers, spectrophotometers, spectrographs, and spectral analyzers are all terms for spectrum measurement instruments.

The study of the absorption and emission of light and other radiation by matter is known as spectroscopy. It entails dissolving light into its constituent wavelengths in the same process as a prism dividing light into a rainbow of colours does. In fact, spectroscopy in the old days was done with a prism and photographic plates. Diffraction gratings are employed in modern spectroscopy to disperse light, which is then projected onto CCDs (charge-coupled devices) like those found in digital cameras. The 2D spectra may be easily extracted and altered from this digital format to produce 1D spectra with a large quantity of valuable data. Spectroscopy is not a specialised or distinct field; it is used in a wide range of disciplines. While it provided a theoretical foundation for early quantum research in radiation and atomic structure, it also has a plethora of other practical applications, including magnetic resonance imaging and X-ray equipment. We used spectra and wavelength to analyse the unique makeup and physical features of far astral bodies, and a sort of radio-frequency spectroscopy is even employed to test doping in sports.

The measurement of the interactions between light and matter, as well as the reactions and measurements of radiation strength and wavelength, is referred to as spectrometry. To put it another way, spectrometry is a technique for examining and measuring a certain spectrum, and it's commonly utilised in spectroscopic investigation of sample materials. Mass spectrometry is a sort of spectrometry that uses the mass-to-charge ratio to determine the mass of a chemical sample. This is commonly accomplished by ionising particles with a shower of electrons, then separating them into different phases of deflection using a magnetic field. After the particles have been separated, they are measured using an electron multiplie, and the mass of each ion is used to determine the sample's composition. Isotope dating and protein characterization are two practical applications of mass spectrometry. Mass spectrometers are also carried by roving space exploration robots such as the Mars Phoenix Lander for the investigation of foreign soils.

Types of spectrometer

Optical absorption spectrometers: The intensity of light is exhibited as a function of wavelength or frequency in these instruments. The distinct wavelengths of light are differentiated by refraction in a prism or diffraction by a diffraction grating. The ultraviolet–visible spectroscopy is one example.

Optical emission spectrometers: Optical emission spectrometers are used to determine the chemical composition of metals with extreme precision. A high-voltage spark is applied to the surface, vaporising particles and forming plasma.

Electron spectroscopy: The examination of electron energy rather than photon energy is used in some types of spectroscopy. One example is X-ray photoelectron spectroscopy.

Mass spectrometer: A mass spectrometer is an analytical tool that measures the mass-to-charge ratio and abundance of gas-phase ions to determine the amount and type of compounds present in a sample.
