SPECTROSCOPY

SPECTROSCOPY

Spectroscopy is the study of the interaction between matter and electromagnetic radiation, which includes visible light, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Spectroscopy provides information about the structure, composition, and properties of matter, including the identity and concentration of chemical elements and compounds.

Spectroscopy can be divided into several different types, including:

Absorption spectroscopy: measures the amount of light absorbed by a sample as a function of its wavelength or frequency. The energy of the absorbed light is used to excite the electrons in the model, providing information about the electronic structure of the model.

Emission spectroscopy: measures the light emitted by a sample after it has been excited by an external energy source. This technique is commonly used to analyse gases' atomic and molecular structures.

Fluorescence spectroscopy: measures the light emitted by a sample after it has been excited by a light source. This technique is commonly used to analyse the presence and concentration of fluorescent molecules in biological samples.

Raman spectroscopy: measures the scattering of light by a sample, providing information about the vibrational and rotational energy levels of the molecules in the sample.

Spectroscopy is widely used in many scientific fields, including chemistry, physics, biology, materials science, and astronomy. It is an essential tool for understanding the properties and behaviour of matter at the molecular and atomic levels, and for developing new technologies and materials.
