| رد : ممكن شرح رامن اسبكترا Raman spectroscopy Raman spectroscopy is a spectroscopic technique used in condensed matter physics and chemistry to study vibrational, rotational, and other low-frequency modes in a system.[1] It relies on inelastic scattering, or Raman scattering of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range. The laser light interacts with phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the phonon modes in the system. Infrared spectroscopy yields similar, but complementary information. Typically, a sample is illuminated with a laser beam. Light from the illuminated spot is collected with a lens and sent through a monochromator. Wavelengths close to the laser line, due to elastic Rayleigh scattering, are filtered out while the rest of the collected light is dispersed onto a detector. Spontaneous Raman scattering is typically very weak, and as a result the main difficulty of Raman spectroscopy is separating the weak inelastically scattered light from the intense Rayleigh scattered laser light. Raman spectrometers typically use holographic diffraction gratings and multiple dispersion stages to achieve a high degree of laser rejection. In the past, PMTs were the detectors of choice for dispersive Raman setups, which resulted in long acquisition times. However, the recent uses of CCD detectors have made dispersive Raman spectral acquisition much more rapid. Raman spectroscopy has a stimulated version, analogous to stimulated emission, called stimulated Raman scattering.

Diffusion Raman La diffusion Raman, ou effet Raman, est un phénomène optique découvert par le physicienindienChandrashekhara Venkata Râman. Cet effet consiste en la diffusion inélastique d'un photon, c'est à dire le phénomène physique par lequel un milieu peut diffuser de la lumière en modifiant légèrement sa fréquence. Ce décalage en fréquence correspond à un échange d'énergie entre le rayon lumineux et le milieu. Cet échange peut avoir plusieurs causes : vibrations du cristal ou de la molécule, excitations magnétiques... La mesure de ce décalage permet de remonter à certaines propriétés du milieu. On parle alors de spectroscopie Raman. Cette technique est largement répandue dans l'industrie et la recherche. Dans le cas particulier ou la diffusion est due à des ondes acoustiques, on parle de diffusion Brillouin. Sommaire ... .. .
