Im. Hedgecock et al., CROSSED MOLECULAR-BEAM STUDY OF THE )-2(X(3)SIGMA(-)(G))-]CRO(X(5)PI(OMEGA))+O(P-3(J)) REACTION(O), Chemical physics, 207(2-3), 1996, pp. 379-387
The Cr(a(7)S(3)) + O-2(X (3) Sigma(g)(-)) --> CrO(X (5) Pi(Omega)) + O
(P-3(J)) reaction has been studied with pulsed, crossed, supersonic mo
lecular beams, at relative translational energies varying between 0.3
and 0.6 eV. The Cr(a(7)S(3)) reactant and the CrO(X (5) Pi(Omega)) pro
duct have been probed by laser-induced fluorescence. The reaction exhi
bits a translational energy threshold at epsilon(tr) approximate to 0.
40 eV. The analysis of the CrO internal energy partitioning just above
the threshold leads to a reaction endoergicity: Delta epsilon(0) = 0.
38 +/- 0.09 eV, and to a CrO bond-dissociation energy: D-0(CrO) = 4.74
+/- 0.09 eV.
