O QUE SIGNIFICA RAMAN SPECTROSCOPY EM INGLÊS
Espectroscopia Raman
A espectroscopia de Raman é uma técnica espectroscópica usada para observar modos de vibração, rotação e outros modos de baixa freqüência em um sistema. Baseia-se na dispersão inelástica, ou na dispersão Raman, de luz monocromática, geralmente a partir de um laser no alcance do visível, do infravermelho próximo ou ultravioleta. A luz laser interage com vibrações moleculares, fonões ou outras excitações no sistema, resultando na energia dos fótons laser deslocados para cima ou para baixo. A mudança de energia fornece informações sobre os modos vibratórios no sistema. A espectroscopia de infravermelhos produz informações similares, mas complementares. Normalmente, uma amostra é iluminada com um raio laser. A luz do ponto iluminado é coletada com uma lente e enviada através de um monocromador. Os comprimentos de onda próximos à linha laser devido à dispersão elástica de Rayleigh são filtrados enquanto o resto da luz coletada é disperso em um detector. A dispersão espontânea de Raman é tipicamente muito fraca e, como resultado, a principal dificuldade da espectroscopia Raman é separar a fraca luz inelásticamente dispersa da intensa luz laser dispersa de Rayleigh.
