Applications of Spectroscopic Techniques to Chemical and Biochemical Problems i) Use in Determining Molecular Structures from Spectra ii) Use in Investigating Reaction Mechanisms iii) Use in Protein Structure Determination. Raman spectroscopy (/ ˈ r ɑː m ən /); (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. The properties of electromagnetic radiation and its interaction with matter leads to variety of types of spectra and, consequently, different spectroscopic techniques and their applications. Main fields of application are the structure elucidation and identification of chemical substances. Advanced Photonics Basic principles: Mechanism and Instrumentation. Part II. This series provides an unequalled source of information on an area of chemistry that continues to grow in importance. Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. # Spectroscopy- Definition Application Advantages # Origin of Spectra # Classification of Spectra. Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. It clearly outlines and describes the principles, advantages, instrumentation, experimental techniques, and noteworthy applications of cutting-edge spectroscopy. Classification of Spectroscopic Methods: Different spectroscopic techniques have been classified mainly on two parameters, first what type of radiation is to be measured or by what measurement procedure is employed. Warm Greetings from Department of Chemistry and Department of Zoology, Mata Gujri College (An Autonomous College), Fatehgarh Sahib, Punjab. Spectroscopic methods are, however, be used in all areas of chemistry. Techniques and Pharmaceutical Application. The absorption spectrum is obtained by applying mathematical analysis to the resulting energy pattern. The spectroscopic techniques described below do not provide a three-dimensional picture of a molecule, but instead yield information about certain characteristic features. [5] The absorption of IR radiation corresponds to energy changes on the order of 8-40 KJ/mole. Radio-frequency spectroscopy of nuclei in a magnetic field has been employed in a medical technique called magnetic resonance imaging (MRI) to visualize the internal soft tissue of the body with unprecedented resolution. 1.
