Abstract

Spectroscopy is a powerful analytical technique used in various scientific disciplines to study the interaction of matter with electromagnetic radiation. This short note provides an overview of spectroscopy, highlighting its principles, applications, and significance in scientific research and industrial applications. Spectroscopic techniques exploit the unique absorption, emission, or scattering patterns exhibited by different substances when exposed to light of varying wavelengths. By analyzing these spectral signatures, researchers can determine the composition, structure, and properties of materials, ranging from atoms and molecules to complex biological systems. Spectroscopy finds widespread applications in fields such as chemistry, physics, biology, environmental science, pharmaceuticals, and materials science. Common spectroscopic methods include UV-Vis spectroscopy, infrared spectroscopy, nuclear magnetic resonance spectroscopy, and mass spectrometry, each offering unique insights into different aspects of molecular behavior and interactions.
