- Search under all synonyms for the property. Example: dissociation constant or pKa or ionisation constant or ionization constant
- Determine property symbol and/or unit.
- Try searching for a substance by CAS registry number, chemical name, molecular formula, and/or structure.
- If searching by chemical name, use various names: Chemical Abstracts (direct or inverted), IUPAC (direct or inverted), common, trade.
- If searching by molecular formula, know how molecular formulas are alphabetized in your source.
Organic compounds: Carbon, Hydrogen, others in alphabetical order
Inorganic compounds: May not be indexed as written
Polymers: Try monomer
Example: CHNO or HOCN
Example: KBr or BrK
Example: SO2Cl or Cl2OS
- Search under the subject area as well as the property name. Example: If looking for extinction coefficient, also try UV
- In print sources, search by using one or more of the indexes. Example: Dictionary of Inorganic Substances has four indexes: Structural Type, Name, CAS Registry Number, and Element
- Use the correct truncation symbol when searching online databases.
- If you can't find your property data using these resources, try a RESEARCH TOPIC search in SciFinder Web. SciFinder Web's natural language searching is useful for retrieving obscure terminology.
