The extensive bands observed from the hehum afterglow reaction of SO\* m the 250-540 mn region are assigned to the new SO+(A \*rt--X\*l$) system produced from the He\*/S02 dissociative charge-transfer reaction at themA energy. They had been erroneously mterpreted as the SO; (c-4 system produced from

✦ Synopsis
(\mathrm{N}{2}^{+}\left(\mathrm{B}^{2} \Sigma{\mathrm{u}}^{+}-\mathrm{X}^{2} \Sigma_{\mathrm{g}}^{+}\right))emission was observed from the near-resonant charge transfer between (\mathrm{Ne}{2}^{+})and (\mathrm{N}{2}). Vibrational populations for (v^{\prime}=0) and 1 of (N_{2}^{+}(B)) were in good agreement with a vertical transtion (Franck-Condon) model The (N_{2}^{*}(\mathrm{~B}) : (\left.v^{\prime}=0\right)) state was rotationally excited and the effective rotational temperature was estimated to be (800 \pm 100 \mathrm{~K})

OCS+ (x-z) emission has heen observed from the thermal energy charge transfer reaction between N; ions and OCS molecules. The rotational temperatures of the OCS+ (A 21T,: O") state were estimated to be 23OOk 300 K for D = 3/2 and 3300 + 500 K for O= 112, by assuming a single Boltzmann distribution.
The charge transfer reaction of He+ with N20 produces vibrationally excited N:(X) ions. The relaxation processes occurring after formation of the NC (X, u" ) ions have been investigated. Charge transfer with N,O is the main relaxation mechanism and its rate does not vary much with the internal energ
