Studies on the Infrared Spectra of a Mercaptotriazole and Mercaptothiazoline and Their Adsorption on Silver Iodide

An investigation has been carried out on the infrared spectra of 3-mercapto-4-methyl-5-ethyl-1,2,4-triazole and 2-mercaptothiazoline, both in solution and in the crystalline form. The spectra of the deuterated compounds and the silver salts have also been examined. The results allow some assignment of bands to be made. The spectra of these compounds adsorbed on silver iodide were then examined. It would appear that in the concentration range examined physical adsorption occurs.
