Abstract
The dissociative excitation of HgBr2 by rare‐gas metastable atoms and N2(A3J+u) has been studied in a flowing afterglow apparatus. Reaction of HgBr2 with the lighter rare gas (He, Ne, and Ar) metastable atoms gave strong Hg* line emissions. Intense HgBr (B2J+→X2J+) emission (300–513 nm) from Xe(3P2) and N2(A) reactions was observed. The rate constants for HgBr* (B) formation from HgBr2 excitation by Xe(3P2) and N2(A) were determined as (5.31.5) ×10−10 cm3 sec−1 and ⩽1×10−10 cm3 sec−1 at 350 °K, respectively. Also, the formation rate constant for HgBr* (C) from HgBr2+Xe(3P2) was determined to be (1.10.3) ×10−10 cm3 sec−1.Keywords
