【摘要】 本文分析了用激光显微拉曼光谱仪测试的楚雄州不同时期、不同地点的 6个恐龙化石样品的拉曼谱 ,确定了其表面主要成分均为 Ca CO3 。实验观察到 2 84cm- 1 (CO2 - 3 的整体振动 )谱峰的强度变化可能与年代相联系。实验结果为建立楚雄州恐龙化石拉曼光谱数据库提供了重要资料。更多还原

【Abstract】 We have obtained and analyzed the Raman spectra of six kinds of dinosaur fossils from three regions of Chuxiong by Micro-Raman spectroscopy.We found that main compound of all dinosaur fossils surface is calcium carbonate (CaCO 3).We find that a decrease in band intensity at around 284 cm -1 due to loss of v (CO 2- 3) stretching vbrations is correlated with the increase in age of the fossils.The result provides valuable dates for database of dinosaur fossils from Chuxiong.更多还原
