Popis:	The interference between the distant and contact excitation quenching in liquid solutions is considered as well as the kinetics of accumulation and dissipation of their products: excited complexes and ion pairs. The contact one starting first is interrupted by a distant one developed later. In highly viscous solvents the distant reaction completely screens the contact one. This fact first demonstrated here within Markovian encounter theory is then essentially extended with the non-Markovian Unified Theory (UT). The latter allows to specify the yields of all the products and their viscosity and concentration dependencies as well as the kinetics of sequential products accumulation and dissipation.
