N2 - CO infrared stimulated emission has been observed from flash-initiated SO2 + XCN (X - Br, Cl, and CN) mixtures. About 36 P(J) lines of vibrational-rotational transitions are present between Δv (13-12) and Δv (5-4) Dilution in SF6 greatly enhances the laser emission, whereas only slight enhancement is obtained from such diluents as Ar and He. Mass spectrometric analysis shows that about 20% conversion of XCN occurs per five flashes at 2.1 kJ and that CO, NO, CO2, and probably some N2 are produced. The reaction, O(3P) + CN(X2Σ) → CO† + N(4S), ΔH1°= -74 kcal/mol, was confirmed to be the major pumping reaction of this system, and O(3P) + CN → N(2D) + CO†, ΔH2° = -19 kcal/mol, seemed to be unimportant on the basis of our laser emission measurements.
