Ultraviolet Absorption Spectra of Derivatives of Symmetric Triazine. I. Amino Triazines

Abstract

The near ultraviolet solution spectra of twenty one mono-, di-, and triamino derivatives of symmetric triazine are reported. The addition of amino groups to the s-triazine ring introduces electrons which can interact with those of the ring, with resultant changes in the intensity and position of the absorption bands. The spectra of mono-, di-, triamino-s-triazine may be arranged in a Platt sequence along with that of trichloro-s-triazine and that expected for s-triazine.
