   <abstract xml:lang="ru">
    <p>Представлена картина распределения электрических зарядов в продуктах присоединения одного и двух протонов к молекуле азобензола в серной и пиросерной кислоте (олеуме). Дикатион (
                  +phNHHNph
                  +) отличается от образующегося в сернокислых растворах оранжевого монокатиона, содержащего фрагмент “phNH
                  +” интенсивным красным цветом. Появление батохромно смещённой полосы поглощения у дикатиона объясняется в рамках представления Симпсона о делокализации электронного возбуждения между уровнями двух локальных (субмолекулярных) хромофоров, в качестве которых выступают фрагменты “
                  +phNH”. В каждом из фрагментов положительные заряды распределяются на атомах углерода в орто- и пара-позициях фенильных колец, как в катионах бензильного и фениламинильного типов. </p>

    <p>The electric charges location in moieties of Azobenzene being protonated in H

                  +phNHHNph
                  +) is showed. In difference to orange mono-cation which obtained in sulfur acid to possess the sub-unit “phNH

                  +phNHHNph
                  + di-cation is red in color. It is found that the red color can be considered in Simpson’s model approach using the idea of delocalized electronic excitation in the molecular sub-units. The chromogen molecular sub-units in mono-cation and di-cation are phNH
                  +-groups which have positive charges allocated in ortho- and para-positions of phenyl rings such as benzyl- and anilino-cation maintain.</p>
