Abstract The photolysis of four chloro-substituted thiadiazoles (3, 4-dichloro-, 3-chloro-and 3- chloro-4-fluoro-1, 2, 5-thiadiazole; 3, 5-dichloro-1, 2, 4-thiadiazole) and 3, 4-dicyano-1, 2, 5- thiadiazole was investigated in inert solid-argon matrices at cryogenic temperatures by means of UV irradiation at selected wavelengths of 254 and 280 nm. The photolysis products were identified by mid-IR and UV spectroscopy. Evidence for the existence of ...
