摘　　要：以表面增强拉曼效应的金面作为基底，用共焦显微拉曼光谱仪对Ｃ６０在紫外光辐射下拉曼光谱的变化进行了原位的跟踪考查。结果表明，在紫外辐射下，Ｃ６０发生了聚合，失去了分子所固有的球形对称结构；但聚合产物的笼状结构形式并无太大的变化，只是结构的共轭体系增大，整体的对称性降低。Raman spectroscopy was applied to monitor the coalescence process of C60molecules induced by UV radiationThe C60 moleculesm,adsorbed on the gold surface,was processed to enhance the Raman scattering effectAs shown by the recorded spectra,after the coalescence reaction,the bands corresponding to the high symmetry Ag mode of the C60 molecules either disappeared or becamevery weak,but the bands of other vibrational mods just broadened and shifted to lower wavenumbersThe spectroscopy result suggests that the products of coalescence still keep the cage structure of the pristine C60 molecules
