   <abstract xml:lang="ru">
    <p>Результаты исследования ассоциации молекул метиленового голубого и кофеина в водном растворе методом спектрофотометрии проанализированы с использованием димерной модели. Выполнено разложение экспериментального спектра поглощения смеси гетероциклических молекул на индивидуальные составляющие. По данным отдельных компонентов спектра (по положению и интенсивности полос поглощения), полученным из сопоставления экспериментальных и расчетных спектров методом регуляризации, проведена оценка в точечно - дипольном приближении структурных параметров гетерокомплекса: расстояния и угла между точечными дипольными моментами переходов разнородных молекул 0,34 нм и 38 о соответственно.</p>

    <p>The results of the study of the association of methylene blue and caffeine molecules in aqueous solution by spectrophotometry were analyzed using a dimer model. The decomposition of the experimental absorption spectrum of a mixture of heterocyclic molecules into individual components is performed. According to the data of individual components of the spectrum (position and intensity of absorption bands) obtained from comparison of experimental and calculated spectra by regularization, the structural parameters of the heterocomplex were estimated in the exact-dipole approximation: the distance and angle between the point dipole moments of transitions of dissimilar molecules 0.34 nm and 38 o, respectively.</p>
