我们已经开发了超拉曼散射显微光谱，并将其应用于全反式β-胡萝卜素的微晶。全反式-β-胡萝卜素的超拉曼光谱在1564 cm（-1）处显示出拉曼非活性但红外活性的振动模式。利用该谱带进行微晶的超拉曼成像。主动振动成像的空间分辨率远高于传统的红外显微镜。拉曼和超拉曼光谱的结合为不受选择规则限制的高空间分辨率振动显微光谱开辟了新的范围。(c)2006年美国光学学会。
We have developed hyper-Raman scattering microspectroscopy and applied it to a microcrystal of all-trans-beta-carotene. The hyper-Raman spectrum of all-trans-beta-carotene exhibits a Raman-inactive but infraredactive vibrational mode at 1564 cm(-1). Hyper-Raman imaging of a microcrystal was performed with this band. Infrared-active vibrational imaging was achieved with a spatial resolution much higher than that of conventional infrared microscopy. The combination of Raman and hyper-Raman spectroscopy opens up a new scope for high-spatial-resolution vibrational microspectroscopy that is not restricted by the selection rule.
