The INDO calculation for clusters LnF85- embedded in CaF2 matrix was carried out. The result has been used to discuss two models currently proposed for the description of the mechanism of paramagnetic shift in rare earth compounds, showing that the polarization model is more reasonable than the covalent model. However, the spin density is transferred not through the polarized Ln(5s, 5p) orbitals as suggested by the polarization model, but through Ln(5d) participation in bonding. The positive isotropic component in the shift tensor of Yb3+ in CaF2 has been explained by valence fluctuation.

本文通过对电介质极化机理的分析,指出大气在光波频率作用下仪需考虑分子的电子位移极化,而对波长较长的无线电波则必须考虑水蒸汽分子的转向极化。根据大气压强、水汽压随高度变化的经验公式,利用光波频率作用下的实验室测定,加上水蒸汽分子转向极化的理论计算,应用克劳休斯——莫索缔方程和麦克斯韦关系式,可作出大气折射率随高度变化的关系曲线。对比大气对光波及无线电波的折射率,可明显看出大气小水蒸汽含量对气体折射率的影响。
