1.喇曼光谱仪发展简介: 1928年,印度物理学家C.V.Raman(喇曼)发现某些分子所散射的一部分光的波长与其入射光的波长不同,波长的偏移(Shift)与分子的化学结构相关。这一发现在早期引起极多的应用兴趣,喇曼因此获得1931年诺贝尔物理奖。由于喇曼谱线的强度甚弱,仅为入射光强度的10~(-8)左右,故早期只能在使用低压汞灯及高浓度样品的情况下应
1. Introduction to Raman spectroscopy: In 1928, the Indian physicist CV Raman found that some of the molecules scattered by a certain molecule have wavelengths different from those of the incident light. Shift of the wavelength and molecular chemistry Structurally related. This discovery has aroused great interest in the early application, Raman won the 1931 Nobel Prize in Physics. Due to the intensity of the Raman spectrum is very weak, only the incident light intensity of about 10 ~ (-8), so early only with the use of low-pressure mercury lamp and high concentration of the sample should be
