## Abstract The Br~2~ elimination channel is probed for 1,2‐C~2~H~2~Br~2~ in the B${{}^3{\rm{\Pi }}\_{ou}^ + }$–X${{}^1{\rm{\Sigma }}\_g^ + }$ transition upon irradiation at 248 nm by using cavity ring‐down absorption spectroscopy (CRDS). The nascent vibrational population ratio of Br~2~(__v__=1)/B
