Integral encounter theory

However, the very first attempt to justify DET starting from the general multiparticle approach to the problem led to a surprising result it revealed the integral kinetic equation rather than differential one [33], This equation constitutes the basis of the so-called integral encounter theory (IET), which is a kind of memory function formalism often applied to transport phenomena [34] or spectroscopy [35], but never before to chemical kinetics. The memory... 

We have seen in Section IV that the study of the reversible reaction of energy transfer was made possible only by means of integral encounter theory. The same is true for reversible electron transfer (3.354) that was first considered with IET in Ref. 188 and then in a much wider context in subsequent publications [107,189],... 

This behavior, inherent to the IET description of either reversible or irreversible transfer, can be eliminated using modified integral encounter theory (MET) [41,44], or an improved superposition approximation [51,126],...
