分布在新西兰马特里海湾的管柱状埃洛石矿物的喇曼光谱可通过 Renishaw 1000喇曼光谱显微镜系统获得。在完整波长范围内,利用喇曼微探针可获得直径仅0.8μm 晶体的喇曼光谱,并可以研究光谱沿不同晶轴方向产生的特定振动。观测到的羟基衍生物的3个频带分别是3616.5cm~(-1)、3623.4cm~(-1)和3629.7cm~(-1),3个频带与埃洛石八面体底部同界面内部烃基之间有密切联系。3698.2 cm~(-1)和3705cm~(-1)的两个频带对应于八面体晶体外部不同界面的羟基。3629.7cm~(-1)频带的相对密度沿埃洛石晶轴倾向产生变化。试验研究还表明,埃洛石的晶格变化也与晶轴倾向有密切关系。
The Raman spectra of the tube-shaped halloysite minerals distributed in the Gulf of Mouty of New Zealand can be obtained by the Renishaw 1000 Raman spectroscopy microscope system. Raman spectra of crystals with a diameter of only 0.8 μm can be obtained by Raman microprobe in the whole wavelength range and the specific vibration of the spectrum along different crystal axis directions can be studied. The three bands of the observed hydroxyl derivatives were 3616.5 cm -1, 3623.4 cm -1 and 3629.7 cm -1, respectively. The three bands were similar to those of the bottom of halloysite octahedron. There is close contact between. The two bands of 3698.2 cm -1 and 3705 cm -1 correspond to the hydroxyl groups at different interfaces outside the octahedral crystals. The relative density of 3629.7cm ~ (-1) band changes along the axis of halloysite. Experimental studies also show that the halloysite lattice changes are also closely related to the crystal axis.
