Spectroscopy is the study of the interaction between matter and electromagnetic radiation. It involves the measurement and analysis of the spectrum of light emitted, absorbed, or scattered by a substance. This technique is widely used in various scientific disciplines, including physics, chemistry, astronomy, and materials science.

The spectrum of light is a range of wavelengths, each corresponding to a different color. When a substance is exposed to light, it can absorb or emit specific wavelengths, creating a unique spectral signature. This signature can be used to identify the substance, determine its composition, and study its physical and chemical properties.

There are several types of spectroscopy, each based on the type of radiation used and the interaction with the substance. Some common techniques include:

- Ultraviolet-Visible (UV-Vis) Spectroscopy: Measures the absorption of ultraviolet and visible light by a substance.

- Infrared (IR) Spectroscopy: Measures the absorption of infrared light, providing information about molecular vibrations and bonds.

- Nuclear Magnetic Resonance (NMR) Spectroscopy: Uses the absorption of radio waves by atomic nuclei in a magnetic field to study molecular structure.

- Mass Spectrometry (MS): Measures the mass-to-charge ratio of ions, providing information about the molecular weight and structure of a substance.

Spectroscopy is a powerful tool for analyzing and understanding the composition and properties of materials. It is used in a wide range of applications, from identifying unknown substances in forensic science to studying the composition of distant stars in astronomy.
