The organ ic impur ities are ver y effec tively d etected in UV spectroscopy. This series provides an unequalled source of information on an area of chemistry that continues to grow in importance. The spectroscopic techniques described below do not provide a three-dimensional picture of a molecule, but instead yield information about certain characteristic features. This work describes experimental techniques using laser spectroscopy and presents specific practical applications for this technology in many fields, including physics, engineering, chemistry, medicine and bioscience. 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. Infrared (IR) spectroscopy. This chapter will present literature studies that applied spectroscopic techniques to nanomaterial characterization, and these studies can be used by the reader to investigate his/her own nanostructured systems. 2. Spectrometry is the measurement of these interactions and an instrument which performs such measurements is a spectrometer or spectrograph. Spectroscopic techniques applied to discriminate soils for forensic purposes Luis Valério Prandel A, Vander Freitas ... Principles, Techniques and Applications’. Main fields of application are the structure elucidation and identification of chemical substances. Gamma-ray Spectroscopy .

National Level Workshop on Spectroscopic Techniques in Structural Elucidation Journal of Chemical and Pharmaceutical Sciences ISSN: 0974-2115 JCHPS Special Issue 5: 2014www.jchps.com Page 24 Mass spectrometry (MS): Analytical technique that measures the mass-to-charge (m/z) ratio of ions from a sample and results in a measurement of relative abundance. These techniques arc the vibrational spectroscopic technique of Raman spectroscopy, and the fluorescence spectroscopic technique of laser-induced fluorescence (LIF). 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.
