The Effective Mass of Base Frame SiCl_2 for Si-H Chromophores Stretching Vibrations in H_2SiCl_2 H2SiCl2分子Si-H振动基座SiCl2的有效质量
The lanthanide contraction shifts the stretching and libration of ( PO_4)~ ( 3-) and Ln O bond vibrations to higher frequencies. The amounts fo shifting are concerned with the structure of Ln O coordinations and PO_4 tetrahedra. (PO4)~(3-)四面体的振动频率对晶体结构很敏感,镧系收缩引起的频移与振动性质以及镧氧配位体、磷氧四面体的结构方式有关。
