spectroscopy
[spɛk'trɒskəpi ]
Definition
scientific technique
Spectroscopy is a technique used to analyze the interaction between matter and electromagnetic radiation. It is often used to identify the composition, structure, and properties of substances by observing how they absorb, emit, or scatter light. Based on the nature of the radiation involved, various types of spectroscopy, such as infrared, ultraviolet, and nuclear magnetic resonance spectroscopy, are employed in scientific research. This technique is widely used in chemistry, physics, and astronomy, providing vital information about molecular properties and the behavior of materials.
Synonyms
analysis, examination, measurement.

Origin of 'spectroscopy'
The term 'spectroscopy' originated from the combination of the Latin word 'spectrum', meaning 'appearance' or 'image', and the Greek word 'skopía', which means 'to look at' or 'to examine'. The concept began to take shape in the early 19th century when scientists started studying light and its interactions with various materials. Early contributions from pioneers like Joseph von Fraunhofer and Gustav Kirchhoff laid the groundwork for modern spectroscopy. The field has since expanded significantly with advanced technologies, influencing a wide range of disciplines from chemical analysis to astrophysics. As a result, spectroscopy has become an essential tool for understanding the fundamental properties of matter.
