UV photolysis ( λ =248 or 255 nm) of cyclic S 2 N 2 isolated in solid argon matrices yields two open‐shell S 2 N 2 isomers, trans SNSN ( 3 A′′) and cis SNSN ( 3 A′′), as well as a closed‐shell C 2v dimer (SN) 2 ( 1 A 1 ). These novel isomers have been characterized by their IR spectra and mutual photo‐interconversion reactions. Quantum chemical calculations support the experimental results and also provide insight into the complex potential energy surface of S 2 N 2 .
