Reliable theoretical descriptions of the reactions $$\begin {array}{ll} (1) &O(^{1}D) + N_{2} = O(^{3}P) + N_{2}\ (2) &O(^{3}P) + N_{2}(v = 1) = O(^{3}P) + N_{2} (v = 0)\ (3) &N_{2}O(^{1}\Sigma^{+}) = N_{2} (^{1}\Sigma^{+}_{g}) + O(^{3}P)\ \end {array}$$ require the calculation of accurate adiabatic hypersurfaces for the low-lying states of the $N2O$ system. Such surfaces are presently being computed for the lowest $\mathrm{<mrow\; data-mjx-texclass="ORD">1</mrow>}A\prime$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">3</mrow>}A\prime \prime$ states. The results and their bearing on Reactions (1)-(3) will be presented and discussed. D. G. Hopper is a NAS-NRC Resident Research Associate.
