✦ Synopsis
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. These values indicate that average energies partitioned into rotation correspond to 39% and 58% of available excess energies, respectively, differing from the Ar+ reaction with similar energetics.
