应用锥形体积中棒状分子旋转扩散的动力学模型计算了棒状分子取向角的一阶和二阶球谐函数的时间自相关函数。数值结果得到的各种相关函数作为一个函数的极角θ0内的分子的轴被限制。介电弛豫，动态光散射和荧光退偏实验的应用指出。
The dynamical model of rotational diffusion of rod‐shaped molecules in a conical volume is applied to the calculation of time autocorrelation functions of 1st and 2nd order spherical harmonic functions of the rod’s orientation angles. Numerical results are obtained for the various correlation functions as a function of the polar angle ϑ0 within which the molecule’s axis is confined. Applications to dielectric relaxation, dynamic light scattering, and fluorescence depolarization experiments are pointed out.
