Structure and Properties of High Temperature Species Related to Ablative Re-Entry and Solid Propellants.

Abstract

The report describes electron-spin-resonance (ESR) and optical spectroscopic investigations of 'high-temperature' molecules. These species have all been observed while trapped in solid argon or neon at temperatures near 4K, i.e., using the matrix-isolation technique. The molecules investigated, and the spectroscopic method employed, are: carbon molecules C4, C5, C6, C9, and their oxides C2O, C3O, in the infrared; rare-earth diatomic and triatomic oxides in the infrared and visible regions; alkaline-earth diatomic fluorides MgF, CaF, SrF, BaF in ESR; diatomic hydrides BeH, MgH, CaH, SrH, BaH, ZnH, CdH, HgH, PdH in ESR. Contributions were also made to the theory of spin-doubling in molecules and to the theory of polytypism in solid silicon carbide. (Author)
