孔雀石和蓝铜矿是自然界最常见的含Cu~(2+)碳酸盐矿物,但很少有人对它们的光吸收进行实验和理论研究。在孔雀石和蓝铜矿中分别只观测到一条和两条谱带,S.V.J.Lakshman和B.J.Reddy在孔雀石中观测到了四条谱带,但实验结果与报道的差别很大。最近,我们研究了几个不同地区孔雀石和蓝铜矿的室温光吸收谱,均观测到了四条谱带,并对结果进行了理论分析。实验所观测到的谱带,都可用配位场理论 Malachite and azurite are the most common Cu2 + carbonate minerals in nature, but few people do experiments and theoretical studies on their light absorption. Only one band and two bands were observed in malachite and cyanite, respectively. Four bands were observed in malachite by S.V. J.Lakshman and B.J. Reddy, but the experimental results differed greatly from those reported. Recently, we studied the room temperature optical absorption spectra of malachite and azurite in several different regions. Four bands were observed and the results were theoretically analyzed. The bands observed in the experiment are all available ligand field theory
