【摘要】 本文考虑光和晶体原子的相互作用,用量子力学微扰理论,计算光作用下晶体原子在一级近似下的电偶极矩。再根据晶体对称性算出晶体介电常数ε,ε张量呈对角形式,可解释晶体的双折射。进一步考虑电矩二级近似得旋光晶体ε有非对角对称的共轭元素,解释了晶体的旋光性。更多还原

【Abstract】 This paper deals with the interaction between light and the crystal atom, calculating the dipole moment of the first order proximity under the action of light by virtue of the perturbation theory in quantum mechanics, and deriving the dielectric coefficient e of the crystal from its symmetric property. It is believed that the diagonal form exhibited by the e tension explains the double refraction phenomenon of the crystal, while the existence of non-diagonally symmetric elements in the dielectric coefficient of the optic-rotayional crystal found by considering the dipole moment of the second order proximity explains its optic rotation behaviour.更多还原
