The kinetics of optically induced anisotropy in molecular complexes with a nonequilibrium rotational distribution arising during their formation in the gas phase are calculated. It is shown that damped periodic oscillations, the period and amplitude of which depend on additional angular moments, appear in the anisotropy relaxation kinetics. The additional angular moments are determined by force moment vectors during translational-rotational exchange taking into account the law of conservation of total angular momentum of the molecules forming the complex. Anisotropy relaxation becomes significantly modulated as their magnitude increases. The estimated degree of optical anisotropy modulation and force moments during chemical bond formation can be used to clarify the stereodynamics of the complex-formation process.

气相分子配合物的光学各向异性的弛豫

计算了在气相中形成过程中产生的非平衡旋转分布的分子络合物中光诱导各向异性的动力学。结果表明，各向异性弛豫动力学中出现了阻尼周期振荡，其周期和幅度取决于附加的角矩。考虑到形成复合物的分子的总角动量守恒定律，附加角矩由平移-旋转交换期间的力矩矢量确定。各向异性弛豫随着其幅度的增加而变得明显受到调节。在化学键形成过程中光学各向异性调制和力矩的估计程度可用于阐明复合物形成过程的立体动力学。
