| Abstract: | Through survey and drawing of the ultraviolet absorption spectrum of benzene,Chlorobenzene and benzene amine aniline solution in absolute ethyl alcohol,this article discusses the influence of auxochrome on benzene and the ultraviolet spectrum of its derivatives.It is revealed in the experiment that when auxochrome is drawn into organic compound moleculor,its structure changes and the maximum absorption warelength of its ultraviolet absorption spectrum mores toward long warelength.Applying this method,study is done on the inberent law of moleculor electrons transition among various energy levels. |
