The time-resolved emission spectrum and its temperature dependence were observed with gaseous CS<SUB>2</SUB> excited by an N<SUB>2</SUB> laser. The spectrum was found to consist of three band systems, one of them being demonstrated to be emission from the <SUP>1</SUP>A<SUB>2</SUB> state. The collision-free lifetimes and the collisional quenching constants were determined for the three band systems. The emission from the <SUP>1</SUP>A<SUB>2</SUB> state was found to be quenched by a magnetic field because of the enhancement of an intramolecular energy-transfer process. This is the first observation of the magnetic quenching of emission from an excited singlet state.
