✦ Synopsis


A laser pulse-and-probe technique

mcorporaling a tunable infrared color center laser is used ICI study the reactIons and quenching of Br(1P,,2. 2 P3,2 ) with 1%. A highly selestive spin-orb11 effecl on chemical reacG<lj is obsewed The ground-slaw reaction, BI-(~P,~)+IB~ + Br2+I, k = (46+0.6)~10-" cm' molecule-' s-' proceeds a~ a rate 2 40 limes faster than the raw of lolaI Br' quenching and reaction with IBr.
