Near Ultraviolet Absorption Spectra of Melamine and Some Related Compounds

Abstract

An absorption band of low intensity has been found in the 2800 to 3400A region for solutions of melamine, trimethylol melamine, trimethyl ether of trimethylol melamine, hexamethylol melamine, and cyanuric chloride. The band has also been observed in gaseous melamine at elevated temperatures. The band is believed to be due to a singlet-triplet transition, rather than analogous to the 2600A absorption system of benzene.
