Spectroscopy

Spectroscopy is the study of the interaction between matter and electromagnetic radiation. It involves the measurement of the frequency and intensity of radiation absorbed or emitted by a substance. This information can be used to identify the substance, study its properties, and analyze its composition.

Types of Spectroscopy

Atomic Spectroscopy: Focuses on the study of the electromagnetic radiation absorbed and emitted by atoms.
Molecular Spectroscopy: Involves the study of the interaction of molecules with electromagnetic radiation.
Electron Spin Resonance Spectroscopy: Specifically examines the behavior of unpaired electrons in a magnetic field.
Nuclear Magnetic Resonance Spectroscopy (NMR): Analyzes the magnetic properties of certain atomic nuclei.
Ultraviolet-Visible (UV-Vis) Spectroscopy: Measures the absorption of ultraviolet and visible light by a substance.
Infrared Spectroscopy: Studies the absorption and transmission of infrared radiation by a substance.
Raman Spectroscopy: Involves the scattering of light by a substance to provide information about its vibrational and rotational modes.

Applications of Spectroscopy

Spectroscopy has numerous applications across various scientific and industrial fields, including:

Chemical analysis and identification
Pharmaceuticals and drug development
Environmental monitoring
Astronomy and astrophysics
Forensic science
Material science and nanotechnology
