α-AlO(OH)水硬铝石晶体简振模的研究(英文)

STUDY OF NORMAL VIBRATIONAL MODES IN α-AlO(OH) DIASPORE CRYSTAL

本文利用群表示理论研究α—AlO(OH)水硬铝石晶体可约表示特征标并找出声学模和光学模变换的不可约表示.根据投影算子技术确定了简振模,我们分析了所得结果并给出了合理的解释.

The character and reduction of the reducible representation for a-AlO(OH) diaspore are investigated using the group theory. In the light of the projection operator technique, the normal vibrational modes are determined. We analyze the given results and make reasonable explanation.
