With this panorama, needless to say that little room existed for the use of Raman spectroscopy as an analytical tool. Looks like you’ve clipped this slide to already. I.R.E., 50, 2367 (1962). Phys. Schematic diagram of the current capabilities of Raman spectroscopy. J. Javier Laserna is Professor of Analytical Chemistry at the University of Málaga. Raman spectroscopy can take advantage of the convenience of a range of instrumental configurations, from dispersive to interferometric systems, from monochannel to multichannel detection schemes, and a wide choice of laser systems for convenience of excitation and filter units for spectral purification. Developments in instrumentation and Raman-related concepts through the 20th century. Thomas, and G.R. 1. If you wish to opt out, please close your SlideShare account. Advantage was taken of the capability for light integration of photographic emulsions to mitigate the Raman detection problem. A historical review, European Spectroscopy News, 72, 10 (1987). See our Privacy Policy and User Agreement for details. With routine limits of detection in the nanogram range and high molecular selectivity, micro-Raman spectroscopy has now become a major analytical technique of application in both industry and research. Such analysis is possible using a Raman microscope. This fact has posed several restrictions to the progress of Raman spectroscopy and had configured to a large extent the instrumentation since the beginning of the experimentation to the present. Water is a very weak Raman scatterer. Written specially for spectroscopyNOW.com by Prof Javier Laserna at the University of Málaga. Acta, 283, 607 (1993). J., 49, 587 (1970). Rev., 21, 483 (1923).

V. Raman in 1928 It is a spectroscopic technique used to observe vibration , rotational, and other low-frequency modes in a system.

- observed frequency shifts are related to vibrational changes in the molecule associated with IR absorbance. R.N.

Kr+, He-Ne, cadmium and ruby lasers were also widely employed. Later, the mercury Toronto arc lamp became the ultimate source since its introduction in 1952 (7).
