✦ Synopsis

Rate coefficients for the reactions ofSH+NzO(v,, 0, O)+HSO(A*A') for vi=0 and 1, and HSO(A2A') +N,O+products, are measured at room temperature. SH is formed by pulsed laser photolysis of H2S and vibrationally excited N20 is created using the stimulated Raman technique. The reaction kinetics are followed by chemiluminescence of HSO. The results show that the reaction between SH and unexcited N,O has a rate coeffkient eaual to 1.3 ( ?r 0.14) X 1 O-" cm3 molecule-' s-', while NzO ( 1 , 0,O) reacts with a rate coefftcient at least 2.2. times larger.
