A generalized statistical-thermodynamical model of hetero-association of aromatic molecules in aqueous solution for the NMR data interpretation

Abstract: На основе базовой модели гетероассоциации ароматических молекул в водном растворе разрабо тана обобщенная статистико-термодинамическая модель для интерпретации данных ЯМР-спек троскопии, В предложенной модели, в отличие от базовой, учтены краевые эффекты, пи е. зависимость химического сдвига протонов от положения молекулы в агрегате-внутри, на краях или в гетеростыке. Обе модели апробированы на примере гетероассоциации акридинового краси теля профлавина (PF) и фенантридинового красителя бромистого этидия (ЕВ) … Show more

“…The monomer concentrations x 1 and y 1 may be derived from the solution of the mass concentration law for scheme (3) [12]. It follows that the model (4) is a function of two unknown quantities, δ h and K h , which may be determined from the concentration dependences of δ (Fig.4a) using the numerical procedure described previously [12,22].…”

“…Model (3) is based on the same physical assumptions which have already been used in previous models of molecular self-association 13,18 and hetero-association [14][15][16][17] and does not introduce any extra limitations to the dynamic equilibrium summarized in equation (2).…”

“…A thorough theoretical analysis of the heteroassociation of two aromatic components with formation of no more than two hetero-stacks in the mixed complex was made previously for the GEN model 17 . Analysis of such a relatively simple case shows that rather complicated mathematical manipulations are needed to calculate the hetero- It is convenient to present the algorithm of the stochastic model in the form of two subprograms: the first one calculates the concentrations of compound X or Y in solution (Fig.1), the second calculates the chemical shift of the corresponding proton of the X or Y compound (Fig.2).…”
