The formulae for linear electric polarization induced by harmonic electric field in liquids composed of rigid noninteracting dipolar and asymmetric-top molecules in spherical solvents are derived. The model of noninertial, anomalous rotational Brownian motion is applied. The fractional rotational diffusion equations are solved and time evolution of the electric polarizability is investigated for the case when a dc-electric field is turned off and for the stationary state case when only an ac-field is present. Numerical analysis of the dispersion and absorption parts of electric polarizability is performed as well as the influence of molecular parameters on so-called Cole-Cole plots is investigated.

球形溶剂中刚性,偶极不对称顶分子的溶液中的异常介电弛豫。

推导了在球形溶剂中由刚性非相互作用偶极子和不对称顶分子组成的液体中由谐波电场引起的线性极化的公式。应用非惯性,异常旋转布朗运动模型。求解分数阶旋转扩散方程,并针对直流电场关闭时和仅存在交流电场时的稳态情况,研究了极化率的时间演化。对电极化率的色散和吸收部分进行了数值分析,并研究了分子参数对所谓的Cole-Cole图的影响。
