spektroskoopias
Spektroskoopias is the branch of science that studies the interaction of electromagnetic radiation with matter. It aims to determine the composition, concentration, structure, and physical state of substances by analyzing how they absorb, emit, or scatter light.
Core principles include energy transitions in atoms and molecules, the emission and absorption of photons, and
Common techniques encompass ultraviolet-visible (UV-Vis) spectroscopy, infrared (IR) spectroscopy, Raman spectroscopy, and fluorescence or phosphorescence spectroscopy.
Applications span chemistry and materials science for composition and purity, biology and medicine for molecular structure
History and development: spectral analysis emerged in the 19th century with discoveries about light and atomic
