Abstract
THE ultra-violet absorption curve of l-hydroxyl benzselenazole in methyl alcohol is almost identica-with that of l-keto-2-methyl-1 : 2-dihydrobenzselenazole, and quite distinct from that of the o-methyl ether. In aqueous sodium hydroxide solution, the curve of the hydroxyselenazole is shifted to the left (deformation), and there is a decrease in maximum due to the production of the ion on which tautomeric change depends.
