Organic spectroscopy: Principles of Organic Spectroscopy

Author(s): Dr. Monika Bansal

Organic spectroscopy is a branch of chemistry that focuses on the study of organic compounds using various spectroscopic techniques. Spectroscopy provides valuable information about the structure, composition, and properties of organic molecules by analysing the interaction of these molecules with electromagnetic radiation. This abstract provides an overview of the fundamental principles and applications of organic spectroscopy. The abstract begins by introducing the basic concepts of spectroscopy, such as electromagnetic radiation, energy levels, and the interaction between light and matter. It then discusses the different types of spectroscopic techniques commonly employed in organic spectroscopy, including infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR), ultraviolet-visible spectroscopy (UV-Vis), and mass spectrometry (MS). Infrared spectroscopy involves the study of the vibrational modes of organic molecules, providing information about functional groups and molecular structure. NMR spectroscopy, on the other hand, investigates the magnetic properties of atomic nuclei in a molecule, offering insights into the connectivity and environment of atoms within the molecule. UV-Vis spectroscopy measures the absorption and transmission of light by molecules, enabling the determination of electronic transitions and the identification of chromophores. Mass spectrometry characterizes the mass and fragmentation patterns of molecules, aiding in the identification and quantification of organic compounds.
