The infrared spectra of a number of new ethers, amino derivatives, and sulfur-containing s-triazines have been obtained in the region between 3333 and 670 cm−1. An interpretation of the spectra is given and some new assignments are made. In addition the existance of certain hydroxy and thiol derivatives in the keto and thioketo configuration is shown.
