天然金刚石的定向红外光谱研究

STUDY ON THE ORIENTED INFRARED SPECTRA OF NATURAL DIAMOND

本文对天然金刚石在垂直于 ( 10 0 )、( 110 )和 ( 111)三个方向上定向红外光谱进行了定量比较分析 ,指出C—H键和C—C键在以上三个方向上的浓度不相同 ,引起C—H键和C—C键在不同方向上的浓度差异是由于氢具有优先取代垂直于 ( 111)方向上C—C键中碳原子的倾向。

Comparisons of the oriented infrared spectra data on the quantitative basis show that there are different concentrations of C-H and C-C bonds in the directions vertical to (100), (110) and (111). Analyzing the concentration differences between the C-H bond and the C-C bond in the different directions, we think that hydrogen tends to replace the carbon atom at C-C bonds which are related to the direction vertical to (111).
