Atomic sulfur $\text{S}\left(3{\text{p}}^4{}^3\text{P}\right)$ was generated in the photolysis of OCS at 248 nm and exited to the $3{\text{p}}^{3}4\text{p}{}^3\text{P}$ state by ultraviolet two-photon absorption at 308 nm. Transfer from the $3{\text{p}}^{3}4\text{p}{}^3\text{P}$ state to the $3{\text{p}}^3\text{4s}{}^3\text{S}$ state by infrared radiation and/or collisions with ambient gases was followed by the vacuum ultraviolet (VUV) fluorescence via the $3{\text{p}}^3\text{4s}{}^3\text{S}$ → $3{\text{p}}^4{}^3\text{P}$ transition at 180 nm. The time-resolved VUV fluorescence intensity was recorded at varying pressures of N₂. Kinetic analyses have given not only the overall rate coefficient for quenching of the $3{\text{p}}^{3}4\text{p}{}^3\text{P}$ state by N₂ but also the branching ratio of the quenching from the $3{\text{p}}^{3}4\text{p}{}^3\text{P}$ state to the $3{\text{p}}^3\text{4s}{}^3\text{S}$ state.
