结合光解光谱，研究光解碎片速度矢量的各向异性，可以推导出依赖于跃迁偶极矩和解离碎片行进方向之间夹角的通量各向异性的表达式。本文推导的公式修正了旋转效应和有限解离速度的简单推导。有限速度下各向异性的损失与热能与平动离解能之比成正比。
In connection with photodissociative spectroscopy, where one studies the anisotropy of the velocity vectors of photodissociated fragments, one can derive an expression for the anisotropy of flux depending on the angle between the transition dipole moment and the direction of travel of the dissociated fragment. The formulas derived here correct the simple derivations for the effect of rotation and finite dissociation velocity. The loss of anisotropy for a finite velocity is proportional to the ratio of thermal energy to translational dissociation energy.
