Different exciting lasers may be used to excite a microscopic sample at different wavelengths so that the Raman microspectrometer can collect and analyze the vibrational spectra. 0 1923 – Inelastic light scattering is predicted by A. Smekel 1928 – Landsberg and Mandelstam see unexpected frequency shifts in scattering from quartz 1928 – C.V. Raman and K.S. In addition, a review of the instrumentation of several nonlinear Raman methods which are based on the second‐order (χ (2) ) and the third‐order nonlinear susceptibility (χ (3) ) is given.

In 1980, he received his Ph.D. from the University of Málaga and during 1986-1987 was a visiting scientist at the University of Florida. <<746FB1A1881F494CBB84F07954363E4F>]/Prev 281105/XRefStm 1166>> Spectroscopy is the study of the interaction of light (electromagnetic radiation) with matter. 0000088238 00000 n These frequencies are in the range of 10 12 to 10 14 Hz, and correspond to radiation in the IR region of the electromagnetic spectrum. 0000002769 00000 n ... His research activities were concentrated on the development and applications of Tip-Enhanced Raman spectroscopy (TERS). 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. 0000007995 00000 n Raman spectroscopy traditionally uses units of wavenumbers (cm-1) to measure the energy shift of the Raman bands relative to the laser line. Now, Raman spectroscopy has become one of the most popular approaches to study the vibrational structures of molecules together with infrared spectrum. 0000019822 00000 n An overview of the fundamentals of Raman spectroscopy and strain … Although some vibra-tions may be active in both Raman and IR, these two forms of spectroscopy arise from different processes and different selection rules. However, as the time elapsed Raman spectroscopy became increasingly important for the advancement of chemical measurements.
