Description	We confront several parametrization schemes which have been used for transfer and relaxation for Frenkel exciton interaction with a responsive bath. Standard projection formalism yields dynamic equations the for single-exciton density matrix complementing the usual single-exciton Liouville equation by adding terms describing the bath influence. The latter terms must, on the other hand be properly parametrized. Using the simplest model systems, namely symmetric dimer in Part I and symmetric trimer in Part II, we found, that a usual parametrization scheme, called the Redfield secular approximation could distort true time dependence of physical quantities calculated by means of exciton density matrix.
