Inorganic Chemistry – The study of the composition, properties, structure, and reactions of the chemical elements and all their compounds with the exception of hydrocarbons and their derivatives. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.
Organic Chemistry – The study of the composition, properties, structure, and reactions of carbon-based compounds, specifically hydrocarbons and their derivatives and normally excluding carbon oxides, metallic carbonates, carbides, and carbon-sulfur and carbon-nitrogen compounds. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.
Physical Chemistry – The application of the laws, principles, and techniques of physics to the study of chemical properties, transformations, and reactions. NASA Thesaurus, Washington, DC: National Aeronautics and Space administration.
Exhaustive Interest : Chemistry of elements and compounds characteristic of NASA's aerospace, planetary, and astronomical interests; combustion theory and processes of direct relevance to aircraft, launch vehicle, and spacecraft materials and propulsion; and low pressure and vacuum reactions.
Negative Interest : Chemical research of elements, processes, and compounds that do not have possible aerospace applications.
