Spectroscopy is a scientific method used to study the interaction between matter and electromagnetic radiation. It involves measuring the spectrum of radiation that has been absorbed, reflected, or emitted by a sample. This interaction provides detailed information about the sample's composition, structure, and physical properties. Different regions of the electromagnetic spectrum, such as visible light, ultraviolet, infrared, and X-rays, are used in various spectroscopic techniques. Each technique probes different aspects of the sample's electronic or vibrational states. For instance, UV-Vis spectroscopy is used to study electronic transitions, while infrared spectroscopy is employed to investigate molecular vibrations. Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for determining the structure of organic molecules by analyzing the magnetic properties of atomic nuclei. Mass spectrometry, though not strictly spectroscopy as it measures mass-to-charge ratio, is often discussed alongside spectroscopic methods due to its complementary role in identifying and quantifying substances. Spectroscopic data is typically presented as a spectrum, a graph plotting intensity against wavelength, frequency, or energy. Analyzing these spectra allows scientists to identify unknown substances, determine their concentration, and understand their chemical behavior. Spectroscopy has wide-ranging applications in fields such as chemistry, physics, astronomy, medicine, and materials science, playing a crucial role in research, quality control, and diagnostics.
