摘要
用量子化学从头计算法(ab initio)计算高岭石内层氢原子和外层氢原子的位置,计算出的内层氢原子平衡位置为:氢氧键与ab平面的夹角为-19.4°,氢氧键长0.098 28nm;外层氢原子平衡位置为:氢氧键与ab平面的夹角为64.4°,氢氧键长0.101nm。
Ab initio hartree-fock calculations have been carried out on the clay mineral kaolinite Al-2Si-2O-9H-4 using STO-3G basis sets. The equi librium position of the inner hydrogen is predicted to be parallel to the (ab) p lane (forming an angle of -19.4°)with an O-H bond length of 0.098 28nm. The eq uilibrium position of the outer hydrogen is predicted to be parallel to the (ab) plane (forming an angle of 64.4°) with an O-H bond length of 0.101nm.
