The time evolution of product-state anisotropy, through absorption or fluorescence, is developed and compared with the experimental observations for three reactions involving elementary and complex dynamics. The reactions are trans-stilbene-He → trans-stilbene + He, ICN → I + CN, and Hgl_2-Hgl + I. Reagant rotation, applied torque, vibrational averaging, and dynamic axis switching are incorporated into the theoretical treatment. The theory is classical in approach, but it describes the experimental behavior on the femtosecond to picosecond time scale, which enables one to obtain the nature of the angular momentum in the final distribution, the structure of the final fragments, and the geometry of the initial complex prepared.
